Biological measures for utilization and development of salinized soil 改良和開發(fā)利用鹽漬化土壤的生物學(xué)措施
Effects of mixture of compost and chick - muck on improvement of salinized soil 內(nèi)蒙古東部地區(qū)鹽漬土資源概況及改良利用
Characteristics and current situation of salinized soil in da ' an city , jilin province 吉林省大安市鹽漬化土壤特征及現(xiàn)狀研究
Abstract : salinized soil in gansu province is mainly distributed in hexi corridor besides a few in lanzhou city and baiyin city 文摘:介紹了甘肅省土壤鹽漬化的狀況,分析了引起土壤鹽漬化的因素,并進行了土壤鹽漬化對生態(tài)環(huán)境損害的經(jīng)濟評估。
In recent years , such problems as the extension and application of on - film irrigation , reclamation of salinized soils , and prevention of secondary salinization have made it important to study coupled movement of soil water , salt and heat transfer under plastic mulch in arid and semi - arid areas 近年來覆膜灌溉的推廣應(yīng)用、鹽堿地開發(fā)和改良以及土壤次生鹽堿化防治等問題使得研究西北干旱-半干旱地區(qū)覆膜條件下土壤水、鹽、熱耦合遷移規(guī)律成為重要課題。
This paper gives a new concept of oasis , and based on theory of sustainable development , it profoundly studys the sustainable development strategies of oasis in hexi corridor and points out that reasonablly utilizating water resource , harnessing desert and salinized soil , developing characteristic industrial , being knowlegeable are the most important pathway in carrying out the suatainable development of oasis in hexi corridor 通過重新定義綠洲概念,結(jié)合可持續(xù)發(fā)展理論對該區(qū)的可持續(xù)發(fā)展對策進行了研究,認為合理利用水資源、治理荒漬化和鹽清化、發(fā)展特色產(chǎn)業(yè)、知識化是實現(xiàn)河西走廊綠洲可持續(xù)發(fā)展的最重要途徑。
