Abstract:
Based on remote sensing and GIS, the spatial-temporal transfer of ecological service value in the past ten years in Guanzhong-Tianshui economic zone is studied. The results show that: (1) The ecological service value in Guanzhong-Tianshui economic zone were 17.853 billion yuan, 26.313 billion yuan and 27.065 billion yuan in 2000, 2005 and 2010, respectively.(2) The ecological service value of Baoji and Shangluo city were in the leading position from 2000 to 2010.From the aspect of spatial transfer,the transfer value was biggest from Baoji to Xi′an city.(3) In terms of land use type,the ecological service value of cultivated land was the most,while the ecological service value of construction land was the least. The transfer of ecological service value mainly occurred in cultivated land, woodland and grassland,and secondly between cultivated land and construction land. (4) The ecological service value in the southern region was higher than that in the northern region of Guanzhong-Tianshui economic zone. There are regional differences of the distribution pattern, and it needs strengthen the protection of the ecological environment in the northern region.
