长春高新区土地利用总体规划对区域环境容量的影响

Influence of Changchun Hi-tech Zone General Land Use Planning on Regional Environment Capacity

土地利用总体规划的影响范围广、时间长,与区域社会经济发展关系密切。采用2005年环境监测数据和土地利用详查数据,应用线性规划法获得长春高新技术产业开发区南区(简称高新区南区)2020年规划用地最佳结构控制指标。高新区南区空气环境现状TSP、SO2、NO2、THC、H2S都有较大的环境容量,地表水不能满足III类水体功能标准,潜水水质超过III类标准,声环境和土壤环境质量良好。影响环境的主要用地类型是居住用地、工业及仓储用地、公共设施用地和绿化用地。土地利用方式的改变将促使区域环境容量发生改变。规划期内高新区南区土地利用微观方向有一定的不确定性,所形成的污染源不能完全定位、定量,应拟定弹性治理措施。

General land use planning is closely related with the regional social and economic development.Its range of influence is wide and the time is long.The data come from environmental monitoring and land use data in 2005.The planning control indices for the best structure of land use in 2020 in the Hi-tech Industrial Development South Zone were obtained by using linear programming.In the study area,TSP,SO_ 2,NO_ 2,THC and H_ 2 S in the air all have relatively high environmental capacity;the quality of surface water can＇t meet the requirements of III class water,however the quality of shallow ground water is higher than the requirements of III class water;The quality of acoustical and soil environment are all right.The main land types of impact on environment are residential land,industrial land,warehouse land,public facilities and green space.The changes of land use accordingly bring on the changes of regional environmental capacity.In planning period,there are some uncertainties for micro land use in the study area and the formed pollution sources will not be located and quantified completely therefore,the flexible governance measures should be developed.
