- 摘要:
- 土地利用总体规划通过土地结构和用地布局对生态环境产生深远的影响，开展其生态环境影响评价对进行科学合理的土地利用决策和保护区域生态环境具有重要的理论和实践意义。以格网为评价单元，结合生态系统服务价值法，通过GIS的空间分析功能，定量评价南川区土地利用总体规划的生态环境影响。评价结果表明：（1）规划方案有效地增加了生态用地的面积，其生态服务价值增加了7 779.36万元，提高了7.69%；（2）规划目标年生态环境状况变化幅度R为正的地区占全区面积的92.32%，只有2.65%的地区生态环境状况明显变差；（3）规划目标年的生态环境整体状况将会得到明显改善，从生态环境保护角度证明了规划方案的科学性和可行性。
- Abstract:
- The overall land-use planning has a profound impact on the ecological environment due to adjusting the land structure and land layout. It will have important theoretical and practical significance on the scientific land use decisions and the regional ecological environment protection that its eco-environmental impact assessment is carried out. Taking the grid as the evaluation unit, combining with the method of ecosystem service value and the GIS spatial analysis functions, the ecological environment impact of the overall land-use planning of Nanchuan District was quantitatively evaluated. The evaluation results showed that: (1) the planning leads the ecological land area to increase effectively and the ecological service value increases 77.793 6 million Yuan that increased by 7.69%; (2) by the planning target year, the area that the ecological environment condition variation R was positive would amount to 92.32% of the total, however, only 2.65% of the region became poor obviously; (3) the overall ecological environment condition would have been improved significantly in the planning target year that illustrated the feasibility of this planning program from the perspective of ecological and environmental protection.
