摘要: 在对江南丘陵典型区域──湖南省攸县的稻田湿地进行分类的基础上,分析了稻田湿地的空间格局和功能,并采用AHP法对其综合效益进行了评价.结果表明,攸县稻田湿地可分为淹育性、渗育性、潴育性和潜育性稻田湿地4种类型,其空间优势度分别为4.17、26.4、12.32和31.25.稻田湿地的能量产投比为4.68,N、P、K的产投比分别为0.59、1.59和1.23,其综合效益为0.66.

Abstract: Based on the classification of paddy wetlands in Youxian County of Hunan Province, theirspatial pattern and function are analysed, and their comprehensive benefit is assessed by AHP method. The results show that paddy wetlands can divided into submerged, percogenic, puddled and gley ones, and their dominances are respectively 4.17,26.4,12.32 and 31.25. The ratio of energy output and input is 4.68, and those of N, P and K output and input are respectively 0.59, 1.59 and 1.23. The comprehensive benefit is 0.66.
