摘要
结合层次分析法对"压力—状态—响应"模型进行了改进,提出具有珠江三角洲平原区特征的恩平市土地资源可持续利用评价的PSR模型,并对模型进行量化和可持续利用评价。分析了引起土地质量变化的机制和过程,揭示了土地资源可持续利用中人地相互作用的关系,计算出恩平市土地资源可持续利用的压力、状态、相应、综合协调度,论证了PSR模型在实际应用中具备可行性和实用性。结果认为,模型适宜在数据较齐备的区域进行量化和分析。指出恩平市土地资源要实现可持续利用,应当合理控制人口增长,集约节约用地,合理开发复垦整理,选取适度的城市化进程。
Combined with the method of Analytic Hierarchy Process, a reusable pressure--state--response （PRS） model is set up to evaluate the sustainable land utilization for the Enping City in the Pearl River re- gion. The transformation process and mechanism of land quality are analyzed and the man--land relationship of sustainable land utilization is revealed. The coordination degree of pressure, state, response, and the com- prehensive coordination degree of Enping are calculated. The study shows that the PSR model can be applied in practice and it should be used in the area which has all kinds of data. The strategies of population growth controlling, intensive and save land utilization, land consolidation and reclamation, and appropriate urbaniza- tion process should be taken in order to achieve the sustainable land use for Enping City.
