摘要
解析了"压力-状态-响应"(PSR)模型的结构和运行原理,结合影响耕地资源可持续利用的自然、社会、经济因素以及各个因素间相互影响、相互制约的内部系统规律,构建了耕地资源可持续利用评价的指标体系,为城市化和工业化进程中耕地资源保护和可持续利用提供参考,以便为下一步开展耕地资源生态质量综合评价奠定基础。
By analyzing the structure and operation principle of the＇pressure-state-response＇（PSR）model,combined the impact factors of natural,socio-economic on cultivated land resource sustainable utilization,the mutual influence and restraint law of the internal system between various factors,the evaluation index system for the cultivated land resources sustainable use was established to provide favorable reference for the farmland conservation and sustainable use in the process of urbanization and industrialization,for fixing the foundation in the comprehensive evaluation of cultivated land resources ecological quality.
