黑龙江省佳木斯市郊区耕地保护的PSR研究

PSR Research on Plantation Protection in Suburban Area of Jiamusi City

受区位条件、土地级差收益和城市经济辐射的影响,多年来城市郊区耕地被大量征占,因此该特定地域耕地保护问题不容忽视。以"压力-状态-响应(PSR)"模型为理论基础,运用主成分分析法,以SPSS软件为手段,分析影响佳木斯市郊区耕地变化的驱动力。研究表明:经济发展、人口、城市化水平和耕地保护政策是影响佳木斯市郊区耕地变化的重要驱动因素。因此,要做好郊区耕地保护工作应从调控土地市场、合理调整产业结构、控制人口增长以及加大耕地保护政策的实施力度等面入手。
