- 摘要:
- 对土地利用进行布局优化以协调经济发展与生态环境保护，通过引入系统保护规划理论，以县级区域为评价单元，构建了生态环境压力测算模型，并对各评价单元的生态环境状况进行定量评价，构建生态用地需求模拟模型。结果显示：（1）处于低压力等级的县市只有13个，处于中压力等级的县市最多，有44个，处于高压力等级的有6个，生态环境状况并不理想。（2）生态用地空缺较大的县市主要集中在江苏北部地区，生态空缺区域分布集中。研究中构建的生态环境压力测算模型及生态用地需求模拟模型，对区域生态环境压力进行评价和对生态用地需求进行模拟，能得到较为符合实际情况的结果，具有一定的实际意义。
- Abstract:
- To optimize the layout of land use coordinating the relationship between economic development and ecological environmental protection has become a hot research topic. On the basis of the introduction of systematic conservation planning theory, the county-level regional was selected as the evaluation units, the the eco-environmental stress model was constructed to, quantitatively evaluate the conditions of ecological environment of the evaluation units, simulation model of ecological land demand was built. The results show that: (1) only 13 counties are at a low pressure level, there are 44 counties at the middle pressure level, 6 conties are at the high pressure level, ecological situation is not ideal; (2) the counties where lack of ecological land is relatively significant mainly concentrate in the northern region of Jiangsu, the distribution is concentrated. The model of eco-environmental pressure calculation and ecological land demand simulation were built in this study to evaluate the pressure on the regional ecological environment and simulate the requirements for ecological land, the obtained result is more realistic, and has a certain practical significance.
