摘要： 论文旨在探讨中国南方丘陵区农业水资源脆弱性的概念及内涵,构建脆弱性评价指标体系并进行定量评价实证研究。首先,在了解资源环境科学领域有关脆弱性研究相关成果的基础上,结合中国南方丘陵区农业水资源系统的特点,给出了农业水资源脆弱性的概念,并分析了其脆弱性内涵。然后,以衡阳盆地为例构建了一个包括自然脆弱性、人为脆弱性、承载脆弱性3个方面12个具体指标的评价指标体系。最后,运用模糊物元模型对衡阳盆地7个县(市)的农业水资源脆弱度进行评判,发现祁东县、衡阳县、衡南县、衡东县和耒阳市农业水资源脆弱度为强脆弱度等级,常宁市、衡山县为微脆弱等级。经验证,评价结果与评价区水资源脆弱性的实际表现比较吻合。

Abstract: This paper aims at discussing the concept and connotation and evaluating index system of agricultural water resource vulnerability in hilly area of southern China.First,based on the analysis of the research result of vulnerability in the field of resource and environmental science,a concept of vulnerability of agricultural water resource which represents the characteristic of agricultural water resource system in hilly area of southern China is formed.Then the connotation about the vulnerability of agricultural water resource is probed.It is believed that the vulnerability of agricultural water resource includes two aspects of water quality and quantity,which consist of natural vulnerability,artificial vulnerability and burdening vulnerability.Finally,an assessment index system which concludes 12 indexes is built to express the vulnerability of agricultural water resource in the aspect of water quantity in Hengyang Basin which represents the typical hilly area in southern China.And the vulnerability degrees of 7 counties in Hengyang Basin are calculated by fuzzy matter element analysis method,the results show that vulnerability of five counties out of the total is serious.It is found by validation that the assessment results are consistent with the practical situation,indicating that the index system and the assessment method are credible.

Key words: agricultural water resource, vulnerability, fuzzy matter element analysis method, Hengyang Basin
