据中国纸业网报道,我国是水资源短缺、水土流失最严重的国家之一。我国人均水资源占有量只有世界平均水平的三成,并被联合国认定为世界上最缺水的13个国家之一。令国人千愁百忧的不只是水资源短缺,还有难以根治的水资源严重污染。水土流失更为严重,流失面积已占国土总面积的近40%。水土流失也是形成非点源污染物渗入水体、污染水质、破坏生态平衡的“隐形杀手”。实践证明,增加森林植被能涵养水源、防治水土流失。由于森林林冠能够有效地截流一部分降水,
According to the China Paper Network, China is one of the countries with the shortage of water resources and the most serious water and soil loss. China’s per capita share of water resources is only 30% of the world average and has been identified by the United Nations as one of the 13 countries that are in short supply in the world. To worry people worry not only water shortages, there are difficult to cure the serious pollution of water resources. Soil and water loss is more serious, the loss of area has accounted for nearly 40% of the total land area. Soil and water loss is also the formation of non-point source pollutants into the water, pollute the water quality, destroy the ecological balance “invisible killer ”. Practice has proved that increasing forest vegetation can conserve water and prevent soil erosion. As the forest canopy intercepts part of the precipitation effectively,
