摘  要:
介绍了农林生态系统调节水资源数量作用,一是现实功能,即截流降水、减少径流、迟滞洪峰的截流作用;二是潜在库容,即涵蓄水源减轻流失、调节丰歉的蓄水能力。截流蓄水功能在不同区域、不同尺度下表现形式并不一致,核算方法也有所不同。为全面地核算该功能,首先要区分两类不同性质的功能和选取尽量简单的核算指标,再根据不同的参数将各子系统分别核算,同时评估人为活动的生态后果。珠江三角洲地区农林生态系统的截流作用并不突出,而蓄水能力非常重要。

摘  要:
The advances of the water conservation functions and assessment methods for Agro-forestry ecosystem are summarized and the operational principles are proposed in this paper.The function can be divided into two categories: one is the water interception effect which can reduce runoff and flooding by intercepting rainfall within an ecosystem,the other is the water preservation effect which can decrease erosion and re-allocate water resources by storing water within an ecosystem.The methods used for assessment should be different according to the specific regions and its scales.For a good assessment,it is necessary to define its functions and sub-ecosystems,to consider human regulation,to choose simple indexes and important parameters.For the Zhujiang River Delta,the water interception effect is not so important,while the water preservation effect is very important.
