基于人粮关系的重庆市土地资源承载力研究
F301; 从人粮关系角度出发,利用土地资源承载力模型和土地资源承载指数模型对重庆市三大经济区的土地资源承载力现状进行了分析评价.研究结果表明:2001～ 2010年间都市发达经济区人口超载,人粮关系紧张；渝西地区人粮平衡,土地资源承载力呈波动上升趋势；三峡库区生态经济区人粮关系总体表现为平衡有余,土地资源承载力呈波动上升趋势；2006年受自然灾害的影响,重庆市土地资源承载力总体表现为人口超载,人粮关系紧张....

The results indicated that： in the developed urban economic zone, the population overloaded, and population - grain relationship was tense ; in the western region of Chongqing city, the land carrying capacity gradually increased, and population - grain relationship was balanced; in the ecological economic zone of T |
