摘要：
This study constructs a directed weighted network among traditional village buildings based on directional similarity and utilizes social network analysis to identify influential buildings affecting spatial order. Key findings include: 1) Centrality Measures; Weighted degree, eigenvector, and betweenness centrality quantify the influence of building nodes in terms of quantity, quality, and importance, respectively. 2) Influential Buildings; High centrality buildings are not necessarily 'star buildings'. Their impact is implicit and local, contrasting with the explicit and holistic influence of 'star buildings'. 3) Community Structure; The village forms seven sub-communities with a modularity of 0.681, reflecting ideal community division. Community consistency is influenced by factors like size, the presence of ancient buildings, and morphology. 4) Spatial Order; Centrality distribution among nodes varies between communities. Communities rich in ancient buildings show a complex, organic order, suggesting self-organization, while those with modern buildings exhibit a more rigid layout, indicating imposed order. This research offers methodological insights for traditional village spatial morphology and provides guidance for conservation and planning.

摘要：
The examination of the characteristic law of traditional village transformation over time represents a vital nexus in cultural heritage preservation and the transmission of vernacular culture. Historical event points were used to augment village development information, facilitating the restoration of the village's historical pattern. Geographical analysis methods, including Standard Deviation Ellipse Analysis (SDSEA), Nearest Neighbor Analysis (NNA), and Source-Destination Analysis (SDA), were employed to explore the characteristics of the village's geographical center of gravity, changes in concentration and dispersion, and functional transfer. The stepwise progression of the village's evolution was investigated, as well as the mechanism of residents' behavior during the evolution process. The results reveal: 1) The spatial evolution of the settlement shows a trend of agglomeration. As time passes, the center of gravity of each functional space gradually converges, and the average distance between elements decreases, resulting in a shift from a dispersed to a clustered distribution. 2) The village space changes from simple to complex due to the conduct of the villagers. Residential behaviors promote the establishment of residential space and the development of public and commercial space. The usage, abandonment, and functional transitions that occur inside the space cause functional zones to nest with each other, resulting in a more intricate spatial structure. 3) Both the degree of change and the preservation of the village's functional space show an increasing trend, indicating that the protection of the built space and the expansion of the unbuilt space occur simultaneously. This represents a developmental trend that is consistent with the social surroundings and the villagers' ambitions.

摘要：
<jats:p>Satellite precipitation products (SPPs) have emerged as an important information source of precipitation with high spatio-temporal resolutions, with great potential to improve catchment water resource management and hydrologic modelling, especially in data-sparse regions. As an indirect precipitation measurement, satellite-derived precipitation accuracy is of major concern. There have been numerous evaluation/validation studies worldwide. However, a convincing systematic evaluation/validation of satellite precipitation remains unrealized. In particular, there are still only a limited number of hydrologic evaluations/validations with a long temporal period. Here we present a systematic evaluation of eight popular SPPs (CHIRPS, CMORPH, GPCP, GPM, GSMaP, MSWEP, PERSIANN, and SM2RAIN). The evaluation area used, using daily data from 2007 to 2020, is the Xiangjiang River basin, a mountainous catchment with a humid sub-tropical monsoon climate situated in south China. The evaluation was conducted at various spatial scales (both grid-gauge scale and watershed scale) and temporal scales (annual and seasonal scales). The evaluation paid particular attention to precipitation intensity and especially its impact on hydrologic modelling. In the evaluation of the results, the overall statistical metrics show that GSMaP and MSWEP rank as the two best-performing SPPs, with KGEGrid ≥ 0.48 and KGEWatershed ≥ 0.67, while CHIRPS and SM2RAIN were the two worst-performing SPPs with KGEGrid ≤ 0.25 and KGEWatershed ≤ 0.42. GSMaP gave the closest agreement with the observations. The GSMaP-driven model also was superior in depicting the rainfall-runoff relationship compared to the hydrologic models driven by other SPPs. This study further demonstrated that satellite remote sensing still has difficulty accurately estimating precipitation over a mountainous region. This study provides helpful information to optimize the generation of algorithms for satellite precipitation products, and valuable guidance for local communities to select suitable alternative precipitation datasets.</jats:p>

摘要：
Geoparks are home to unique and precious geological sites and have a rich historical and cultural heritage. Most studies have focused on their tourism value and/or educational significance. However, far too little attention has been paid to the impact of geopark construction on the local ecological environment. The Xiangxi UNESCO Global Geopark (XXGG) was used as a case study to explore the impact of global geopark construction on local ecological quality. Three ecological indices, including an ecological quality index based on productive, residential, and ecological land use, an improved remote-sensing ecological index (RSEI-2), and net primary productivity (NPP), were adopted to evaluate the ecological quality of XXGG during two periods: before construction (from 2015 to 2017) and during construction of XXGG (from 2018 to 2020). The results show that: (1) in general, all ecological quality indicators showed a downtrend (from 2015 to 2017) followed by an uptrend (from 2018 to 2020), indicating that construction and development of XXGG has had a significant positive effect on local ecological quality. This occurred because a series of environmental protection measures were taken after application to the United Nations Educational, Scientific, and Cultural Organization (UNESCO) Global Geoparks (UGGPs) for membership at the end of 2017. (2) The areas of XXGG with excellent and improved ecological quality are mainly distributed in the northern and southeastern portions, which are located in the protected area with high coverage rates of forest and other vegetation. Poor ecological quality in the east and south is closely related with human activities, such as ethnic tourism development. The results explore the relationship between regional construction of the geopark and ecological effects and provide a scientific reference for sustainable development of global geoparks.

摘要：
Traditional residences are among the most important tangible cultural heritage. This paper evaluates and explores the quality of individual traditional residences and the heritage value of a complex of traditional residences in Western Hunan in China. The former indicates how well the external characteristics of the building are preserved, whilst the latter refers to the integration of use values, ecology principles and cultural features. Based on the survey of the selected 7 traditional villages, the authors have built a spatial database of these villages on the strength of GIS, RS and GPS techniques, and employed an architectural evaluation method to grade the exterior quality of individual traditional residences, followed by the construction of an evaluation indicator system and the use of entropy weight method to score the value of traditional residences, thereby systematically unveiling how indicators influence the value of traditional residences. The results reveal that well-preserved and prime-quality traditional residences are quite rare. Average-quality individual traditional residences outnumber other quality levels in all selected traditional villages. These villages differ in the value of their traditional residences, which is susceptible to both natural and cultural factors. Architectural elements play a dominant role, and the change in architectural form serves as an important criterion for determining whether the traditional residence in question has been transformed into a modern building. The value of traditional rural residences is mainly reflected in the authenticity of the architectural form and the building material, which are crucial to the intact pass-down of their unique architectural styles.
摘要：
Traditional villages are the carriers of tangible cultural heritage and intangible cultural heritage,as well as China’s non-renewable cultural resources and valuable tourism resources.With Sina travel blogs as the data platform,taking the number of page views as an evaluation indicator of network attention,the dynamics of network attention to the 91 traditional villages in Hunan Province that have been included in the first three batches of Chinese Traditional Village List were analyzed from two aspects of time and space.Based on this,development strategies were put forward for tourism of Chinese traditional villages so as to promote the development of the tourism economy in Hunan Province.
