Study On Ecological And Environmental Effects Of Regional Land Use Change In Urumqi

In the research of land science and ecological science, evaluation of land ecosystem service function has been the international and domestic hot spot and the focal point question.Based on the research achievements at home and abroad on the land ecosystem service function value evaluation in this paper, taking Urumqi city as the research object, taking the city of Urumqi from 2003 to 2013 ten years of data of land use change and the yearbook data as the data source, using the improved land use ecosystem service function value assessment model accounting for the city of Urumqi land use static value of the ecosystem service function and value of the dynamic analysis of land use in Urumqi City, and analyzing the each administrative region distribution of land use ecosystem service value, ecosystem service function value distribution, in order to reveal the human activities of land resources utilization and social and economic development of the ecological environment, puts forward suggestions for land use of Urumqi City, and provide scientific basis for the sustainable use of land resources to promote. This paper gets the following conclusion:(1) in 2003-2013, Urumqi city land use structure changed greatly;(2) Urumqi city static ecosystem service value is on the rise in 2003-2013, the region of land ecosystem service function value of static space distribution;(3) Urumqi land ecosystem service value of dynamic and static land ecosystem services value is proportional to the relationship, to the rise in 2003-2013; by contrast, the land use change of ecosystem service value of dynamic fluctuation is bigger;(4) Urumqi city land affected social production technology advanced degree is the most important factor in ecosystem service function value.
