| 摘 要： | 在综合分析土地资源可持续利用主要观点并提出土地资源可持续利用实现目标的基础上，从资源、环境、经济和社会4方面构建了适合县城经济发达地区特征的土地可持续利用评价指标体系，共选择了25个参评因子。然后对江阴市1991年、1994年和1997年的土地资源可持续利用状况进行了综合评价。结果表明，自20世纪90年代以来，随着江阴市社会经济的不断发展，江阴市土地资源利用的可持续性也日益增强，处于基本可持续状态。但是，1997年与1991年相比，资源、环境两要素的可持续性分别下降了10.35%和12.23%，若不加以重视，可能在一定的时期内会导致江阴市土地资源开发利用的不可持续性。为了进一步提高江阴市土地资源开发利用的可持续性，文章认为，必须从人口数量控制、用地结构优化、环境污染控制以及增加农业投入等4个方面加强管理。

| Abstract: | Based on the analysis of the conception, objectives, principle and content of sustainable land use, in light with actual conditions of the Jiangyin city, an indicator system for evaluating county level sustainable land use was put forward, including 25 evaluating indicators of resources, environment, economic and social aspects. The comprehensive evaluation of sustainable land use for Jiangyin city in 1991, 1994 and 1997 was conducted, resulting in 59.26%, 62.13% and 63.85% of the evaluation value respectively. This indicated that land use in Jiangyin was in an sustainable situation. But from 1991 to 1997, the sustainability ratios of resources and environmental aspects decreased rapidly by 10.35% and the 12.23%, respectively. So problems also exist in land use in Jiangyin such as acute man land conflicts resulted from rapid reduction of cultivated land and population growth,serious industrial pollution and weakening of ecological function, and ignorence of agricultural development and unreasonable structure of agricultural sectors. Measures for coping with the above mentioned problems and for future sustainable development are also identified as to control population growth and protect cultivated land, to optimize land use structureand achieve dynamic balance of cultivatedland, to control pollution and improve environmental quality, and to increase agricultural investment and combine farming, forestry, animal husbandry and fishery. |
