| 摘 要： | 地形差异性导致的环境异质性为小尺度范围内生物空间格局的形成与维持提供了一种重要机制,是形成物种丰富度差异性的前提条件.借助GIS和S-PLUS软件,利用广义可加模型(GAM)于7-8月对影响蝗虫分布的地形因子进行了研究,在定量分析黑河上游祁连山区北坡地形的海拔分异特征的基础上研究了该区域蝗虫的丰富度与地形复杂度的关系....

| Abstract: | The environmental heterogeneity caused by topographical diversity is an important mechanism underlying the formation and maintenance of bio-geographic pattern of diversity distribution at the micro-scale,and the prerequisite for the difference in species richness.With the help of GIS and S-Plus,the GAM model was used to study topographic indexes influencing the distribution of grasshopper from July to August,and the relationship between the regional locust richness and terrain complexity was also studied ba... |
