Applying analysis of ecological benefit from local land use in reconstructed land configurations

Analyzing the ecological benefits from different land utilization ways comparatively, by means of the evaluation of ecological service value, set a strong fulcrum for choosing rational land utilization way, and became the key point in land use pattern at present, especially in local scale. Therefore, by taking Shapingba district of Chongqing city as an example and rectifying the coefficient of ecological service value raised by Costanza, this paper respectively monetized the ecological service value of each land use type in 1996 and 2009, and then analyzed the spatial-temporal characteristic of that change during the fourteen years, and finally stipulated the future pattern of land use at local level. It came to the conclusions as follows. Firstly, the total ecological service value during 1996-2009 in Shapingba District not reduced but increased slightly. Secondly, the coefficient values of cultivated land, garden land, woodland raised by Costanza were close to regional actualities while that of water land, compared with that of the lake/river assigned by Costanza, was more than true value. Thirdly, the future pattern of land use in this region had four trends: the descend-to-rise zone, the sustainably-increased zone, the stable zone and the sensitive zone.
