土地转移流视角下土地利用变化过程追踪方法探讨 ——以宁夏中部干旱带盐池县为例
Study on tracing method of land use change process based on the perspective of land use transfer flow —A case study in Yanchi County in arid area of central Ningxia Hui Aotonomous Region
摘要
Abstract
Based on the perspective of land use transfer flow , this paper put forwarded the concepts of land use transfer rate and the land use transfer chain , using data sources of Landsat MSS /TM/ETM remote sensing image , and made a comparative study of land change process in Yanchi County in Arid area of central Ningxia Hui Aotonomous Region . The results showed that the area of cultivated land and grassland have increased in the county , however , the area of unused land has reduced during 1978—2015 . At county scales , land use transfer rate rised up and then declined in Yanchi County . At type scale , cultivated land transfer rate was with a feature of fall-rise-fall , grass transfer rates continue to reduce , and unused land with a feature of rise-fall-steady pattern .It is given priority to flows such as unused land to cultivated land flow and grass land to cultivated flow from 1978 to 1987 . The land use transfer flow present diversified from 1987 to 1996 . In Yanchi County , it is given priority to with ecological construction , one-way chain is mainly the type 63 (unused-grass ) , give priority to with Ⅱ type a reciprocating chain ,for the type 363(grass-unused-grass) , the type 313(grass-land-grass)and type 131 (cultivated-grass-land) , a complex chain is mainly the type 163(arable-unused-grass) .关键词
