- Abstract:
-
Industrial transformation of resource cities due to the exhaustion of mineral resources affects the urban land use and eco-environment situation. The coordination of development relationship between land use and eco-environment has an important meaning for changing the traditional urban land use pattern and promoting the harmonious development between human and nature. With 1990,2000 and 2011,3 periods landsat TM satellite remote sensing images of Baiyin resources city as the main data source,land use change characteristics and effect on the ecological environment were analyzed and evaluated based on the ENVI software from 1990 to 2011, and using several kinds of mode, such as single land use type dynamic degree model, dynamic transfer matrix, regional ecological environmental quality index model, regional ecological environmental quality contribution index model. The results showed that construction land area has been growing, cultivated land area firstly increased and then decreased, unused land area has been in reducing trend, woodland, grassland,water area changed little because of their small initial area in Baiyin city during 21 years; ecological environment quality will develop toward a healthy state overall because ecological environment quality index increased from 0.087 to 0.126; contribution rates of cultivated land and unused land were the highest to ecological environment quality improvement, while contribution rates of forestland and water were the highest to ecological environment quality degradation in BaiYin city where cultivated land,unused land water were key factors affecting the regional ecological environment change,and cultivated land was the dominant factor among all factors.
