Abstract:

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, SO₂, NO₂, THC and H₂S 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.

Key words: Changchun City, Hi-tech Industrial Development, land use planning, environmental capacity
