地统计学分析方法在水生态系统研究中的应用
AN APPLICATION OF GEOSTATISTICAL ANALYSIS IN FRESHWATER EC OSYSTEM
-
摘要: 简要介绍了地统计学分析方法的发展和在生态学中的应用情况,提出了将这种方法应用于水生态系统空间格局分析的可能性,然后用梅子垭水库水体藻类叶绿素a含量为例对其浓度场的水平2维空间格局进行了分析,并以此确定了叶绿素a在整个空间和不同方位上空间格局的变化情况。Abstract: The development of geostatistical analysis and it s application in ecology is reviewed in the paper,following with the possibility analysis of spatial pattern in freshwater ecosystem.As a preliminary study,this paper makes use of geostatistical method to analyze horizontal two dimension s patial pattern of concentration field of algea chlorophyll-a in Meiziya Reservo ir,by which we can determine the variation over all study range(isotropic) and i n different direction(anisotropic).
