县域土地资源可持续利用研究——江苏启东市的实证分析

启东市土地资源具有后备资源丰富，开发复垦潜力大，土地利用率较高、土地利用经济效果区域差异较大，农村居民点布局分散、土地整理潜力较大的特点，但随着进一步的开发利用，启东市土地资源将发现出以下若干非持续性的特征：人口不断增加，人均耕地逐年减少，土地污染严重，耕地质量进一步下降；土地利用区域差异较大，发展不平衡；土地养用矛盾突出，滩涂围垦难度加大等。在上述分析的基础之上，提出了启东市土地资源可持续利用的战略目标，然后提出了启东市土地资源可持续利用的对策与措施，包括科学编制规划，建立土地利用规划实施体系；加强非农用地管理，建立严格的农地保护制度；充分利用丰富的水面资源，加强滩涂开发；优化土地利用结构。调整用地布局；激励农民对耕地的投入，制定多种“用”“养”结合的措施。

The land utilization in Qidong County of Jiangsu Province is of following characteristics:higher utilization rate,diversified utilization pattern,scattered distribution of rural residential areas.In general,the land resources are rich in this county and have potentials for further arrangement and exploitation.By analyzing the land resources for the future utilization,it is pointed out that the factors limiting the land utilization are the increase in the population,the in-balanced development in economy in different parts,the conflict in the maintenance and utilization of land resources,the great difficulty in the reclaim of land from beaches.The strategies and effective measures for the sustainable use of the land resources have therefore been proposed.
