基于转移矩阵的景观空间转移指数的提出及景观面积变化的综合分析——以新疆于田县为例
The Comprehensive Analysis of Landscape Space Transfer Index and Area Changes Index
【摘要】 景观在一定时期最重要的变化是景观面积的变化和景观斑块在空间上的变化。在景观面积转移矩阵和景观面积总量变化的基础上,构建了景观空间转移指数和景观面积变化指数,使用这2个指数对新疆于田县平原绿洲及荒漠区进行了分析,结果表明,该区各类景观空间转换强烈,而面积总量变化不大,空间转移指数远大于面积变化指数,说明干旱区景观具有特殊的空间波动性和敏感性,而人为景观(人工绿洲)则具有一定的稳定性和扩张性。由景观面积转移矩阵计算出的景观空间转移指数为综合指标,可以反映一定考察期内景观的空间转化强度,有利于不同景观类型及不同时期景观变化强度的对比,同时景观空间转移指数与景观面积变化指数结合分析,还可以反映景观的某些宏观性变化特点。
【Abstract】 Changes for the landscape area and landscape patch Transfer in space is the most important changes of landscape in certain period.Base on the landscape transfer matrix and landscape total area change,this paper put forward landscape space transfer index and landscape area changes index,and use these two indices onto the landscape change of Yutian County in Xinjiang.The result shows that all landscape types of landscape have obvious conversion,and little change in the total area,space transfer index is much larger than area change index,arid landscape has a special space fluctuation and sensitivity,and man-made landscape(artificial oasis) has a certain of the stability and expansion.The space transfer index which compute from landscape transfer matrix is one comprehensive index,can reflect the space conversion degree of certain period,studio scene view,being advantageous to the landscape change degree of different landscape type and different periods.The Comprehensive Analysis of Space transfer index and area change index,can also reflect some macroscopic change characteristics of landscape.
