摘　　要：选取云南省红塔区2000年、2005年、2010年的3期TM影像以及2015年、2020年的两期高分一号WFV影像为数据源,通过RS监督分类功能及GIS相关功能,获取红塔区生态用地变化信息。利用转移矩阵分析生态用地数量变化以及生态用地面积转移、变化情况,对红塔区生态用地的总体特征、生态用地与非生态用地以及生态用地内部的相互转化特点进行研究。结果表明,2000—2020年间,耕地面积大幅度减少,由2000年的9.4%下降到2020年的5.8%,林地和水域面积比重略有上升,林地和水域的保留率较高;在生态用地向非生态用地的转化过程中,建筑用地主要向裸地和耕地转化,水体大部分转化为建筑用地和裸地,但转移面积较小,林地主要向裸地转化,且转移面积较大,耕地主要转化为建筑用地和裸地,裸地主要转化为了建筑用地、林地和耕地。促使红塔区生态用地变化的驱动因素包括自然因素和人文因素两大类。随着红塔区经济发展,受城市扩张、人口增长等因素的影响,耕地大面积减少,导致生态用地数量和格局发生变化。Using TM images of 2000,2005 and 2010 and GF-1 WFV images of 2015 and 2020 as data sources,this paper obtained the information of ecological land use change in Hongta District of Yunnan Province through RS supervision and classification function and GIS related functions.Transfer matrix was used to analyze the quantity change of ecological land and the transfer and change of ecological land area,and study the overall characteristics of ecological land in Hongta District,the mutual transfer characteristics between ecological land and non-ecological land,and the internal transfer characteristics of ecological land.The results showed that from 2000 to 2020,the arable land area decreased significantly,from 9.4%in 2000 to 5.8%in 2020,and the proportion of forest land and water area increased slightly with the higher retention rate;in the transfer from ecological land to non-ecological land,construction land was mainly transformed into bare land and arable land,most water area was transformed into construction land and bare land,but the transfer area was small,forest land was mainly transformed into bare land,and the transfer area was large,arable land was mainly transformed into construction land and bare land,and bare land was mainly transformed into construction land,forest land and arable land.The driving factors of ecological land use change in Hongta District included natural factors and human factors.With the economic development of Hongta District,affected by urban expansion,population growth and other factors,a large area of cultivated land decreased,resulting in changes in the quantity and pattern of ecological land.
