【摘要】 对紫金县2013年水灾中绿化作用"问题"进行了探讨,提出下述观点:①森林树木本身在雨水分配中,减少降水水量作用是有限的,只有森林土壤才能起到调节径流、减少径流和蓄水防洪作用,而森林土壤需要森林一定时间培育才能形成;②不是任何林型都能够造就森林土壤所特有的土壤结构,只有天然林、生态林、水保林等混交林、乔灌草等复层植物群落下,才能培育出良好的透水、蓄水、调节地面径流、涵养水源的森林土壤。并提出了相应的抚育管理和改造林型的建议。更多还原

【Abstract】 afforestation Problem in Zijin flood in 2013 was discussed in this paper. Conclusions have been made as follow: the function of forest in the distribution and interception of rainfall was limited. Only the forest soil could regulate runoff,storage rain and prevent flood,but it needs a long time to form forest soil. Only soil under mixed forest,such as nature forest,ecological forest,forest used for soil and water conservation and so on,and complex plant communities composed of trees,shrubs and grasses can form the peculiar texture owning to forest soil that can be permeated well by water,regulate stream flow and conserve water recourses.Suggestions on the forest cultivation,management and transformation is also put forward.更多还原
