Land Use Spatial-Temporal Change in the Upper Reaches of Minjiang River

Abstract

The Land use is the concrete manifestation of the relationship between man and land, and it is the result of the comprehensive action of natural and human factors. This paper takes the upper reaches of Minjiang River as the research object, through obtaining MODIS MCD12Q1 data, combining with MRT and GIS software, using land use transfer matrix method, structural analysis method and dynamic degree analysis method, focuses on the three periods of 2001, 2009 and 2013. The results show that there is an increasing trend in the area of forests and waters, and the bare area is fuller utilized, this shows that during the study period, the land structure in the upper reaches of the Minjiang River has been optimized and land use changes have become more reasonable.
