森林水文效应森林对蒸发、降水、径流等水平衡要素及河流、地下水、泥沙等水文情势的影响。又称流域森林影响。对蒸发影响 森林地区的降水，为林冠枝叶和林下枯枝落叶层截留。截留作用主要发生在降雨初期，一次降雨最大截留量有一定的数值。林冠枝叶截留的雨量最终消耗于蒸发，它与散发量（通过根、茎、叶向大气逸散的水量）、林内地面蒸发量共同构成林地蒸散发。林地蒸散发中散发量占很大比重，地面蒸发量较小。气候湿润，有充沛水分供给蒸发的地区，森林对流域的蒸散发影响不大；气候干燥，水分供应不足的地区，林区蒸散发比非林区大。对降水影响 各家看法出入很大，一般认为由于林冠大量蒸腾，林区上空水汽含量增多，湿度大；大气中水平气流经森林阻碍被迫抬升等，都有利于降水；林区内多水平降水。苏联卡明草原58年观测资料表明，森林地区降水量比空旷地区大 9％。中国的野外调查及实验资料也有这样的现象。但亦有不少资料表明，森林对降水没有影响或影响甚微。林下土壤的下渗强度一般比非林地要大得多。这与林地落叶层能减缓地表径流流速、森林土壤中根系发育、土壤中有机质多、团粒结构发育等有关。据中国科学院地理研究所在陕西省黄龙林区的测定，林地的稳渗率比周围的耕地和草地都大。对径流影响 包括对洪水、枯水、年径流量和径流年内分配等的影响。对于一次孤立的洪水，森林有明显的降低洪峰、减少洪水流量、延缓洪水过程的作用。对于连续洪水，林区洪水流量通常比非林区大。在一般情况下，流域内林区枯季径流量比非林区大，年内分配也较均匀。森林对年径流的影响比较复杂。森林流域年径流量比无林流域小，森林砍伐后会使年径流量增加。大面积森林随气候和下垫面性质不同，其结果也大不相同。苏联在喀尔巴阡山南北坡36个流域内的调查表明，年径流量随林率的增大而增加。中国通过对比流域分析表明，北方干旱地区年径流量随林率增大而减小（石质山区除外），南方湿润地区则相反。从热带到温带，年径流量均因森林砍伐而增加，造林后则使年径流量减少。对地下水影响 较为复杂，一般认为山区森林下渗的水量对地下水补给有利；平原森林对地下水影响随气候条件不同而异。对生态环境影响 森林能防止土壤侵蚀。流经林区的河流通常含沙量低，水质好。森林砍伐后河流含沙量、有机物等增加，主要表现在硝酸盐含量大为增加。森林对人类生态环境的显著作用，已越来越引起人们的重视。森林水文效应的研究对开发和营造森林，对环境质量的控制和改善均有重要的意义。20世纪初，瑞士、美国和日本等国就开始进行有林地和无林地的对比试验及森林砍伐对径流影响的研究。中国除进行试验流域对比分析外，还采用了流域模拟等方法。森林水文效应涉及到森林、水文、气象、土壤等多方面的问题，关系复杂，不同自然条件差别甚大，很难以一概全。尤其是在精确的实验测定基础上得出的局部地区的水文效应，很难推广。今后会通过对各地区、各种自然条件下的水文效应实测资料,在水量平衡的基础上进行综合分析,找出一般规律，为改善人类生态环境，提供依据。参考书目R.Lee,Forest Hydrology,Columbia Univ.Press,New York,1980.
