Analysis on Land Use/Cover Change Characteristics and Driving Forces in Guansi River Valley of Mianyang City
摘要
Abstract
This study aims at revealing how land use/cover changed in Guansi River valley which is an important area of protective forests in the upper reaches of Yangtze River. Based on the data of TM remote sensing images in 1995 and IKONOS remote sensing images in 2005, this paper examined the characteristics of the quantities, structure and spatial distribution of LUCC, analyzed the driving forces of the LUCC during the past 10 years. The results showed that the major land covers in the study areas are infield and forestland. During the period of 1995 to 2005, the area of infield and rural housing land decreases markedly and other land use types are increased to some extent. Traffic lands dynamic change index was largest, followed by forestland's. In short term, socioeconomic progress and formulation of the macro policy are major factors on influencing the land use changes.关键词
