- Abstract:
-
Base on GIS, the temporal and spatial land scape changes and ecological risk change in Jinlinwan were studied by using two periods of the land use maps, which were land use status map and land use planning map. Then we determined the weight values of the ecological risk from different land use patterns by analytic hierarchy process and construct integrated ecological risk index of different periods. The results indicate the land types mainly shift from forest, arable land to construction land before and after planning, which the new construction land will locate in ≤ 2° and 6°~15° belts, in line with the mountain land-slope gradient stratification development model of Yunnan Institute of Economic Research, the ecological risk index value of the whole region will rise from 0.045 807 to 0.098 554, the ecological environment will become deteriorated. The Leijiazhuang villagers’ committee in Leijia town will become one of the key areas. This research could provide scientific reference for land use planning and ecological environmental assessment in Yunnan.
