摘要
把循环经济理念引入到土地资源的可持续利用评价领域,并结合江苏省的实际情况,构建基于循环经济的土地资源可持续发展的评价体系,利用层次分析法确定指标权重。评价体系研究结果表明:江苏省基于循环经济的土地资源可持续利用地域差异变化较大,综合指数南部地区大,北部地区偏小,且大部分地区有待于进一步提高;体系控制层指数分析发现:土地投入区域差异较大,土地再循环指数偏低,还有很大的提升空间,部分地区生态环境与社会经济发展不协调,经济社会效益的取得仍然在一定程度上是以牺牲生态环境为代价。病例诊断结果表明:各个地区障碍因素的影响程度差别比较大,按障碍因素的障碍度排序可以分为7个类别。各地区可以根据评价以及诊断结果因地制宜,切实做到土地资源的循环利用和可持续发展。
The concept of recycling economy is introduced to the evaluation systems on sustainable use of land resources. Considering the actual situation in Jiangsu Province, the evaluation systems on sustainable use of land resources has been established. AHP is used to determine indicators＇ weight, the results are as follows： Totally, the regional differences in Jiangsu Province are large. The composite index in the Southern parts is big while that in the Northern is small and in most regions the index needs to be improved further. In some regions, disharmony exists between ecological environment and the development of social economy. To a certain extent, the economic and social benefits are obtained at the cost of sacrificing the ecological environment. The diagnosis shows that the differences among the impact of obstacles vary greatly and seven types can be obtained according to the degree of obstacles. As a result, each region can act according to the estimate and the diagnosis and make sure that the land resources are used circularly and sustainably.
