  eco environment
So the eco-environment in arid China is in a severe condition.
      
Specifically, it is realized through planting grassland and improving local eco-environment.
      
Now we can successfully monitor and forecast the eco-environment in Beijing and neighbor areas.
      
Accordingly, the factors including nature and human activities are crucial to mountainous eco-environment vulnerability with feature of vertical-belt.
      


The effect of acid precipitation on soil acidification and aluminum leaching was investigated by using static equilibrium method.It was observed that the buffer capacity of soil is rather great and the contribution of acid rain for acidifying soil is insignificant. However, the effect of acid rain on aluminum leaching is evident and the nature of soil itself such as acidity 'humus content or temperature also plays an important role .The amount of aluminum leaching for acidic soil is much larger than that for...

The effect of acid precipitation on soil acidification and aluminum leaching was investigated by using static equilibrium method.It was observed that the buffer capacity of soil is rather great and the contribution of acid rain for acidifying soil is insignificant. However, the effect of acid rain on aluminum leaching is evident and the nature of soil itself such as acidity 'humus content or temperature also plays an important role .The amount of aluminum leaching for acidic soil is much larger than that for alkaline soil. Hence, it may be seen that the acid precipitation in southwest China is a potential problem to the local eco-environment.

用静态平衡法探讨了酸性降水对土壤酸化及铝溶出的影响。实验结果表明:土壤对酸的缓冲能力较强;酸雨对土壤酸化的贡献甚微,但对土壤中活性铝的溶出却有明显效应。另外,土壤本身的特性(如酸碱度,腐殖质含量及温度等)也起很大作用。对于地质条件相近的土壤,由于本身的pH值不同,铝的溶出量差别很大,一般而言,酸性土铝的溶出量高于碱性土。因此,可以推断:我国西南地区酸性降水可能对当地土壤生态存在着潜在的危害。

The plantation of trees and graases is an essential project with great strategic significances in the improvement of eco-environment and the develop-ment of local economy in arid regions. But successes can only be gained withsuitable trees and grasses planted in suitable areas, not everywhere random.According to the physical geographic conditions and water resources distr-ibution in Hexi arid region, the author works out its favorable plantationareas as follows: The Qilianshan Mt. plantation area with natural rainfalls, theHexi Corridor plantation area with shallow ground water supports and the He-xi Corridor plantation area with artificial irrigations. The harmonious coordination and cooperation of commercial farming,stock raising and protective afforesting should be the prevailing orientationabided in the constructicn of Hexi's agriculture.

种草种树,是改善干旱地区生态环境,促进经济发展的根本大计,具有战略意义。但在干旱地区不是随处都能种草种树,只有选择适宜地区才能成功。根据自然地理条件和水资源分布特点,河西有条件种草种树的地区可划分为:祁连山天然降水宜林宜草区,河西走廊灌溉宜林宣草地区和河西走廊浅埋地下水宜林宜草区。种树可保护水源,防护农田,制止风沙,使农业稳产;种草能保持水土,促进畜牧业发展,增加肥料,改良土壤,使农业高产。因此,草和树不仅能保证和促进河西商品粮基地的建设,而且也是其不可缺少的重要组成部分。商品性农业,保护性林业和商品性牧业三者协调,相互促进,不断发展,是河西农业建设的正确方向。

Starting with classifying the landform units and based on studying thefactors affecting them and their patterning characteristics, the paper present-ed a model for the construction of ecological land sample plot, providingscientific basis for regulating the agro-production structure and improvingthe eco-environment.

本文从土地形态单位分类入手,在研究影响土地形态单位结构因素与格局特征和属性特征的基础上,提出土地素标准人工生态样地建设的模式,为调整农业生产结构,改变生态环境提供科学依据。
