摘要:
在综合分析湖北省农业水土资源空间分布特征及其匹配格局的基础上,采用DPSIR概念模型建立农业水土资源承载力评价指标体系,利用熵权TOPSIS方法对湖北省17个地区农业水土资源承载力进行定量研究。结果显示:不同地区农业水土资源承载力水平存在较大差异,其中神农架林区和恩施自治州水土资源承载力基本为盈余状态;荆门、仙桃、潜江、天门、武汉、荆州6市水土资源承载力以安全承载为主;随州、襄阳、孝感、宜昌、黄冈5市水土资源承载力以临界超载为主;十堰、鄂州、咸宁、黄石4市水土资源承载力一直呈超载状态。2000—2015年,只有荆州市水土资源承载力等级呈现显著提升。针对不同地区农业水土资源承载力现状提出了应对措施。研究可为合理配置水土资源、促进水土资源可持续利用和社会经济可持续发展提供科学依据。

Abstract:
Based on a comprehensive analysis of the spatial distribution characteristics and matching patterns of agricultural water and soil resources in Hubei Province, the DPSIR conceptual model was used to establish an evaluation index system for agricultural water and soil resources carrying capacity, then entropy-weight TOPSIS was constructed to evaluate the carrying capacity of agricultural water and soil resources (CCAWSR)in Hubei Province. The results showed that there is a great difference in CCAWSR in different regions. CCAWSRs of Shennongjia and Enshi are surplus. CCAWSRs of Jingmen, Xiantao, Qianjiang, Tianmen, Wuhan and Jingzhou are safe. CCAWSRs of Suizhou, Xiangyang, Xiaogan, Yichang and Huanggang are nearly overloaded. CCAWSRs of Shiyan, Ezhou, Xianning and Huangshi have been overloaded. Only CCAWSR of Jingzhou has improved significantly from 2000 to 2015. Finally, some solutions were put forward according to the status of CCAWSR in different areas. The results can provide a reference for rational allocation of agricultural water and soil resources and promote sustainable use of resources and sustainable socio-economic development.
Key words:  Agricultural water and soil resources  Carrying capacity  Entropy-weight  TOPSIS  Hubei Province
