Analysis on Land Use and Cover Based on Markov Model in Xining City
摘要
Abstract
Using land use types dynamic ( UTD) and land use general type dynamic (GTD) , the characteristics of land use changes in Xining City were analyzed, at the same time, the characteristics of land types conversion were analyzed based on Markov model. The results showed that GTD was 0. 15% in Xining City. Land use types dynamic (UTD) of the garden land was the largest and the minimum was the grass land. Cultivated land were from grass land and other lands, and mainly transformed into town and mining land; forest land were from cultivated land and grassland as well as other lands, and mainly transformed into construction land; the grass land were transformed into cultivated land and forest land, no source; only rural residential land turned into cultivated land, the main source was agricultural land which occupied 78.49%. In sum, during 2015 -2020, the cultivated land will increase first and reduce then, and decrease by 614.97 hm2 generally, the grassland will decrease continually and decrease by 329.91 hm2, construction land will increase 567. 63 hm2.关键词
