聊城翻譯公司關(guān)鍵字：precipitation and runoff, groundwater transfer between the regulation and storage. In our construction of water conservation forest, soil and water conservation under the forest, can not form a deep litter layer and the "sponge layer", forests conserve water, soil and water conservation feature is unable to play.Fourth, topographic differentiation of the vegetation types of the law. Terrain through the ups and downs, such as on the slope towards the re-zone climate differentiation, so that翻譯公司報(bào)價(jià) different parts of the terrain showing a different biological habitat in the mountains form a high-Yan Shen vertical change of the vertical band, often referred to as vertical zones of the law. Fractionation of topography on climate and vegetation vertical zones of ecological construction in the law is content to be special consideration. Ecological construction should be a mountain mountain ecosystem rehabilitation and construction, play mountain ecosystems翻譯價(jià)格標(biāo)準(zhǔn) conserving water, soil, the formation of water supplies around the region and climate linkage effect. Mountain precipitation and more evaporation less, suitable for grass bushes and trees have a variety of plant life and diverse environment in this area, based on altitude, soil and other environmental conditions, the vertical band, the establishment of appropriate vegetation type, the likelihood of success large, cost-effective significant. Another point is that do not involve farmland, also near settlements lot easier than the management and protection. Ecological construction of the first phase of our work should focus on this type of area, from easy to difficult and gradually open, you can gain experience in this area, to facilitate follow-up.2, ecological construction and advanced science and technology must be developed using a combinationHuman ecological construction is the main force, but must rely on advanced science and technology in order to achieve the intended purpose as soon as possible, and in this regard many of our region and the entire western China are still very backward. To say that desertification itself, our fight against desertification in the use of new technology, the advanced level at home and abroad there is a great gap between Israel's water-saving irrigation techniques, such as Russia and U.S. chemical fixing, United States, Canada and Western Europe, anti-erosion farming technology in China is still blank.
