- Abstract:
- According to land use classification based on the leading function of ecology, production and living, the land use data of Changli County in 2009, 2012 and 2015, the methods including land used transfer matrix, gravity center model, index of regional eco-environmental quality and ecological contribution ratio of different kinds of land change, and using ArcGIS 10.2, GS+7.0， Excel tools, we quantitatively analyzed the characteristics of land functional structural and spatial transformation as well as its eco-environmental effects. The results showed that: (1) land use changes in Changli County was chiefly manifested as the area increase of productive land and living land, stability of living-ecological land and decrease of ecological land and productive-ecological land; (2) the index of eco-environmental quality in Changli County reduced from 0.330 in 2009 to 0.325 in 2015, therefore the overall quality had been deteriorated; the area and proportion of high quality area remained relatively stable, and the lower quality area, medium quality area and higher quality area constituted to the main body of land use environment; (3) from 2009 to 2015, there were two trends of ecological improvement and deterioration in Changli County. In the whole, the eco-environment quality of land use pattern declined slightly. The critical factor of eco-environmental degradation was the large occupation of agricultural productive-ecological land by other productive land and rural living land.
