凉水自然保护区景观格局变化研究

采用ARC/INFO和景观空间模型———马尔柯夫模型方法,系统分析凉水自然保护区三个时段的景观动态变化。研究结果表明:凉水自然保护区景观格局发生了变化,景观斑块种类增多,并有景观类型增加和减少现象发生,基质———天然红松林的面积在逐年减小,其景观类型转变规律与统计资料、调查资料及林木的内源演替过程相一致;通过景观动态分析,提出今后管理的建议。

Study on Landscape Structure Changes in Liangshui Nature Reserve

This paper deliberated systematically the landscape dynamic changes of three periods in Liangshui Nature Reserve. With the methods of ARC/INFO and landscape space model-Markov model, the research indicated the landscape structure in Liangshui Nature Reserve has changed and the types of landscape patches have been increased. The research found that the phenomena of adding and reducing landscape types happened at the same time, the matrix-Pinus Koraiensis reduced its area year after year. The regular pattern of landscape types' changes went on well with the result summarized from research data, statistics and the developing process of forest's inherent changes. The paper put forward management suggestions for the future through the landscape dynamic studies.
