| 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 You-clan County of Hunan Province, theirspatial pattern 'and function are analysed, and their comprehensive benefit is assessed byAHP 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. 32and 31. 25. The ratio of energy output and input is 4. 68, and those of N, P and K outputand input are respectively 0. 59, 1. 59 and 1. 23. The comprehensive benefit is 0. 66. |
