摘要:
 通过定位监测磨盘山的典型森林植被常绿阔叶林2016年6-9月的大气降雨、穿透雨、叶面积指数等资料，针对林分内各影响因子对穿透雨的空间异质性进行综合分析。结果表明：1）研究期间，2016年6-9月的降雨总量为688.9 mm，大部分为低雨强、低历时、中雨级的降雨。通过观测数据显示林内穿透降雨总量为443.7 mm，占总降雨量的64.41%，平均穿透雨的变异系数为44.7%。2）对林下9个观测点的穿透雨量及林木结构数据进行综合分析，发现大气降雨量与穿透雨量呈正相关关系，叶面积指数与其呈负相关关系。3）通过Kriging插值绘制出空间分布图，图像表明雨量较小时各观测点林内穿透雨的大小分布与观测点上方的林木结构有密切关系，雨量较大时穿透雨的分布更随机，规律性较小，受其他随机因素影响更多。
Abstract:
 By in situ monitoring,indices,such as atmospheric rainfall,through fall,leaf area of the evergreen broad-leaved forests in Mopan Mountain during June to September 2016 were measured to comprehensively understand the impacts of different factors on the spatial heterogeneity of the through fall.The results showed 1) during the study period,the total rainfall was 688.9mm,with the characteristics of low rainfall intensity,short duration and moderate level.The through fall was 443.7 mm,accounting for 64.41% of the average rainfall,the average coefficient of variation was 44.7%.2) After the comprehensive analysis on forest structure and the through fall about the nine observation points,it was found that the through fall was positively correlated with rainfall and negatively correlated with leaf area index.3) The map of spatial distribution that was drawn by using Kriging interpolation indicated that a close relationship existed between the through fall and forest structure when the rainfall was small,when the rainfall was heavy,the distribution of the through fall was irregular,which was affected more by other factors.
