生态系统适应性已成为全球变化与发展的热点问题。生态系统适应性演变是全球变化区域响应的重要表现。我国南方丘陵区是典型的稻作农业区,研究其农业生态系统适应性十分重要。文章以衡阳盆地为例,从自然、社会、经济3个方面选择12个指标构建农业生态系统适应性评价指标体系,评价单元分为衡阳市区及其各县域,以1999-2014年共16年为研究时域,用熵权法确定指标权重,计算衡阳盆地的适应能力指数。结果表明:衡阳盆地农业生态系统适应性总体状况较好,其空间分异较复杂,耒阳市的适应能力最强,祁东县次之,常宁市最弱。时间演变表现为波动上升的特点,评价时域16年分为3阶段: 1999-2004年为适应性小幅度振...

There is renewed interest in the evolution of the adaptability of ecosystem to global change. It is important to study rice farming regions in hilly areas of Hengyang Basin. As a rice-based agricultural region, it is very important to study the adaptability of agricultural ecosystem (AAE) in South China. Previous studies have shown that in Hengyang Basin, a typical agricultural ecosystem in South China, obvious spatial distribution patterns of AAE were higher in periphery regions and lower in the middle regions of the basin. However, the temporal and spatial variation characteristics of AAE we...
