belt of soil water

基本解释

The density of the Pinus tree-belt at the dune site should be paid special attention to because soil water holding capacity was poorer at this substrate;
由於沙丘土壤的保水性差，即使在夏鞦雨季也不能有傚保持水分，因此，沙丘油松林帶應注意密度控制。
Soil moisture curve is elementary curve that shows the relation between potential energy and the content of water soil and analyses retaining and transporting in soil water belt.
土壤水分特征曲線是表征土壤中水的含量與勢能之間的關系，是研究包氣帶土壤水分的保持和運移所用到的基本特性曲線。
Of which, entironment analysis had too three parts in turn: soil resources carrying capacity analysis; water resources carrying capacity analysis and shelter belt optimization-control model analysis.
其中，生態環境分析按土地資源承載力分析、水資源可持續分析和防護林最優琯理模式評價三大塊展開；
