Causes of flood and drought and Countermeasures
. Is to prevent encroachment of the desert, protecting soil and water conservation Heyuan ecological barrier, and has great economic potential. It should be placed equal importance to agriculture, increased investment and governance grassland construction. The momentum to curb desertification. Construction of Aerial shrub and grass planted and the combination of the implementation of education shrub and grass cover the sand. To restore vegetation. Prohibited unauthorized reclamation, digging, hacking, Luancai. To protect the green state. Rational allocation and utilization of water resources, in particular, protect the Tarim River,[link widoczny dla zalogowanych], the lower reaches of the River Determined to implement a grass livestock, stocking limits, household contracting. Sand development industry,[link widoczny dla zalogowanych], to create a Network, a diversified, integrated development. The source area of rivers, should be designated as nature reserves. Indiscriminate hunting is prohibited arbitrary arrest, control rodent pests. Prevent grassland degradation and desertification. At the same time, the distribution of the East Banbi forest climate zone of low mountains,[link widoczny dla zalogowanych], the formation of secondary forest destruction grass.

Zip Code: 430070 [Editor Qian Bo] (Continued from page 16) is not the development of grazing industry,[link widoczny dla zalogowanych], ecological zones, should be barren hills. Radical flood and drought. VIII. Should be implemented on the paid use of natural resources and ecological compensation system, the rational use of natural resources, ecological environment protection and construction, to ensure environmental and economic sustainable development. Natural resources are limited, constitute the elements of the ecological environment and infrastructure, on the overexploitation of natural resources upon request. Inevitable destruction of the ecological environment, waste of resources, and caused serious natural disasters. Against sustainable development. Therefore compensation for the use of natural resources, the system should be implemented to protect and make rational use of natural resources. Legislation of the country as soon as possible: Pu Jian Yuan, Xichang City Bureau of Forestry. Zip Code: 615000 method. Such as land, forests,[link widoczny dla zalogowanych], grasslands, fresh water, biological, mineral resources, landscape and other compensation for the use of natural resources. Also, because the forest is farmland, grasslands, pond and reservoir, lakes, rivers and other protection and support systems. The core of the ecological environment, so the response of forest resources by more forest ecological compensation system. Only in this way. Can fundamentally solve the problem of forest protection and development, and truly solve the problem of mountain environment. Address the sustainable use of water resources to address the scourge of the Chinese nation have long plagued - water, drought and sandstorm disasters. China's environment and economy to ensure sustainable development. (Editor Huai-Jin)
