农业水灾是洪水对农业水灾脆弱性作用的结果。减灾就应从减少洪水的发生频率和降低农业水灾的脆弱性入手。由于科学水平的限制，目前人类还很难改变洪水的发生过程，那么降低农业水灾脆弱性就成为减灾的主要措施，为此灾害脆弱性评价就成为灾害研究的热点问题。灾害脆弱性可以看成是生态安全性的另一面，故加强生态安全建设可以降低农业水灾脆弱性。文章以湖南省为例，选取汛期降水、森林覆盏率、农民人均收入等8个指标，对88个县域的农业水灾脆弱性进行量化评价。在此基础上进行脆弱性区划，并提出具体的生态减灾措施。

Agricultural losses result from not only the risk of hazards but also the vulnerability of flood-waterlogging disaster. It is critical to identify methods for minimizing the manifestation of flood-waterlogging flood-waterlogging condition and reducing agricultural vulnerability to flood-waterlogging. The vulnerability of land-based production systems to natural disasters is a function of the systems, underlying ecological integrity. Therefore, ecological improvement and reconstruction may reduce agricultural vulnerability to flood-waterlogging. The vulnerability of agriculture to flood-waterlo...
