通遼翻譯公司關(guān)鍵字：optimize an effective way. Ecosystem is the parent system, agricultural system, agricultural system is the subsystem of the ecosystem. At the same time, the entire ecosystem is a natural substance based agricultural systems翻譯價(jià)格標(biāo)準(zhǔn). Ecosystem is the unity of biology and environment, biological environment can not be left alone. For agricultural biotechnology, the natural environment is their survival and development. Natural environment is not only required to provide biological material and energy, but also has regenerative capacity, if appropriate measures can continue to be compensated. Matter and energy are constantly living biological communities and between non-living environment into circulation. This is a simple biosphere. In this life cycle contains a natural environment, economic environment, production, and many other aspects of the impact factor, if the agricultural system engineering activities are not sufficiently comprehensive to consider any one factor, it is possible to destroy the ecological balance, sustainable agricultural systems翻譯價(jià)格標(biāo)準(zhǔn) weaken development and optimization, and even lead to economic losses and adverse ecological consequences.Update performance of the agricultural systems翻譯價(jià)格標(biāo)準(zhǔn) for the agricultural ecosystem succession. When the agricultural system in the quantitative phase, we should strive to promote the agricultural system to achieve ecological balance. When the agricultural system will be fundamentally changed, the ecosystem should be to create conditions more conducive to the interests of humanity toward the direction of development. This relates to the agricultural systems翻譯價(jià)格標(biāo)準(zhǔn) of control and optimization problems. Southern Ningxia's agricultural poor natural conditions, especially the severe drought, the local people's survival and development caused great difficulties. A large number of historical data show that deforestation, reclaiming land from lakes, serious damage to the natural ecological balance, is caused by below normal rainfall, frequent natural disasters, the objective factors. Therefore, the change in Southern Ningxia Agricultural thin, thick, dry face, so that翻譯公司報(bào)價(jià) toward increase production, increase production and improve the ecological environment in the direction of light on the efforts in farming is not enough, we must take overall control, optimizing the structure and rational use of agricultural natural resources and advantages to forest protection in agriculture, to promote agriculture, animal husbandry, forestry, animal husbandry take the comprehensive development of
