The drivers and ecological effects of spacio-temporal dynamics farmland in Yanqi Basin
摘要
Abstract
Using statistic data and based on multivariate statistical analysis and literature survey,the dynamics and drivers of farmland changes in Yanqi Basin within 1988-201 1 were analyzed and the effects of farmland change on eco-environment were studied.Results showed that:(1)The changes of farmland area in Yanqi Basin within 1988-2011 were fluctuated,and total area of farmland increased during the study period .The total area of farmland increased from 76 .25 ×104 hm2 in 1988 to 135 .70 ×104 hm2 in 201 1,while it increased 178%with the net increase of 59 .45 ×104 hm2,and the changing trends of total farmland area were similar among counties;(2)The main drivers of farmland dy-namics in Yanqi Basin including government policy,economic development,population increase and the progress in agri-cultural techniques;(3)Farmland dynamics has improved the eco-environment of Yanqi Basin to some extent,whereas resulted in a series of eco-environmental problems such as desertification around the outer oasis,salinization in the inner oasis,and degradation of lake and wetland,which have been threatening the stability of the oasis .Results of the study could provide scientific basis for reasonable use of farmland resources of oasis,and for maintaining ecological security and sustainable development of oases in arid land .关键词
