water sustainable 中文意思是什麼

With the development of human society, because of the lack of sustainable utilization consciousness, and the eager for quick success and instant benefit, the black earth suffered excessive cultivation and management, causing the reduction of its recycled ability, decrease in organic content, porosity ratio, fertility dropped and the properties of water retaining and water retention, which make the black soil harden and degenerate seriously

但是隨著人類社會的發展，在缺乏保護和可持續利用意識、急功近利思想影響下，黑土遭到過度墾殖和掠奪式經營，人類對其活動范圍遠遠超過了其再生能力，導致有機質含量減少，肥力下降，孔隙比減小，保水持水能力降低，土壤板結，黑土嚴重退化。

Soil is the base of agriculture production, the key measure to prevent water and soil loss is to conserve soil, but most soil nutrient is lost with the sediment loss, and serious water and soil loss make the soil thickness degrease, the soil nutrient be deficient and lean, the land quality degrade and the yield of plant decrease, all this results is going to threaten the people ' s transplanting and the agriculture sustainable development, and restrict the economy development of three gorges regions

同時，土壤是農業生產的根本，治理水土流失的關鍵是要保住土壤，而土壤養分絕大部分是隨著泥沙流失的，嚴重的水土流失造成土層淺簿、養分貧瘠，土地質量退化，產量下降，對三峽庫區移民工作和農業可持續發展造成嚴重威脅，制約三峽庫區經濟發展。因此進行三峽庫區坡耕地土壤侵蝕機理研究，探索減輕坡耕地土壤流失的方法措施，具有全局性的重大意義。

The dissertion, after introducing physical geography situation and societal economic sitiuation of chongqing, has also analysed the basic feature of water resources in chongqing, at present the water resources utilization in chongqing is still in traditional phase. there are so many faults and shortcomings in water resources management system. the construction of water resources institutions and regulations is fallen behind. the supply of water resoures has not sufficiently satisfied the demand to water resources. the condition of water quality has not radically improved. soil losses is still serious. the incidence of flood and drought is very high. in accordance with present condition of water resources utilization in chongqing, the dissertion argues that it should strengthen people ' s understanding to water resources sustainable utilization for chongqing ; reform the present water rexources management system and have a try on water affairs management system in chongqing ; make effort to construction of water resources " institutions and regulations ; realize demand management, constuct save - water model society ; according to actual condition, strength water utilization constrution, then realize the balance between water resources supply and demand ; according to the idea of " control resources, conduct flow ", control water pollution, realize sanitary generation ; control soil losses and protect water enviroment ; construc t the system of flood control and diaster prevent

在對重慶市的自然地理情況和社會經濟情況作了介紹之後，還分析了重慶市水資源的基本特徵，目前重慶市的水資源利用還處在傳統的開發利用階段，水資源管理體制還存在許多弊端，水的法規制度建設也相對落後，水的供給還不能完全滿足需求，水質狀況沒有得到根本性的改善，水土流失還很嚴重，水旱災害發生的頻率比較高。針對重慶市水資源利用的現狀，本文提出：應加強對水資源持續利用的認識；改革目前重慶市的水管理體制，嘗試水務局管理體制，相應加強水的法規和制度建設，實現需水管理，建立節水型社會；根據實際情況，加強水利建設，實現水的供需平衡；依據「控源導流」的思想控制水污染，實現清潔生產；治理水土流失，保護水環境；建設防洪減災體系。
