摘要： 论文以江西省鄱阳湖区为例,综合运用特尔菲法、层次分析法、聚类分析法等多种定量分析方法,建立了鄱阳湖区土地健康的评价模型,并运用该模型对该区11个县的土地健康状况进行了评价。评价结果表明,鄱阳湖区的土地健康状况不容乐观:只有德安县为健康区,进贤、九江和永修3县为亚健康区,其它7个县均为不健康区。并进一步对各县土地健康状况的主要表现特征进行了总结,从而可为各地土地资源的合理利用提供指导。

关键词: 土地健康评价, 定量分析, 鄱阳湖区

Abstract: Land health evaluation plays an important role in keeping land health and realizing sustainable land resource utilization.The Poyang lake area,situated to the north of Jiangxi province,includes11counties around Poyang lake and covers an area of about 19873.24km 2 .This region’s ecosystem plays a key role in Jiangxi province and middle and lower reaches of the Changjiang River,however,the ecosystem has become unhealthy with lower stability and produc-tivity,and is more frequently hit by natural disasters.It is thus very necessary to evaluate the health situation for the sake of sustainable development of socio-economy in the region.This paper,taking Poyang lake area as a case,making use of some quantitative analytical methods including Delphi,AHP and clustering analysis,sets up land health evaluation model and applies it to11counties land health evaluation in this area.The land health conditions of11counties were divided into3classes:healthy zone,sub-healthy zone and unhealthy zone.The main health representation of each county was also analyzed so as to provide guidence for rational land resource utilization.

Key words: land health evaluation, quantitative analysis, Poyang lake area
