    摘要:

    该文在野外实验观测和室内分析化验的基础上,分析研究了坡耕地经过综合治理后,生态效益显著提高的几个方面:1.减水减沙效益显著;2.植被覆盖率增加,改善了田间小气候;3.土壤蓄水保墒能力明显增强;4.农田生态系统开始向良性循环转化;5.自然灾害减少,农业抗灾能力增强。

    Abstract:

    Based on the field experimental observation and lab analytical tests, this paper analyses and studies the biological benefits from the cultivated slopping farmlands after the comprehensive controllin water and soil losses, and its biological benefits are shown in the following aspects: 1.the remarkable reduction of water and sediment losses; 2 .an increase in vegetation cover so as to improve microclimate in the fields; 3 .an obvious enhancement in soil ability to store moisture and con- serve moisture in soils;4 .farmland ecosystem begins to convert into a better cycle, and 5.the diminishment of natural disasters and the enhancement in the hability to resist disasters in agriculture.
