Tianshui Plant Resources and Development and Use - to be ornamental plant germplasm

Product are few. Control soil erosion. Must adhere to the Therefore, rational use and protection of resources, we must adhere to the flood control and watershed conservation, afforestation, grass combine in a comprehensive way. According to Weihe River north of the To restore vegetation. Not only unreasonable to gradually reclaimed farmland on steep slopes to forests and pastures, its a lot of hills, but also to speed up the gully planting trees and grass. Particular attention to the development of both fertilizers, fuel, feed the role of C. intermedia, Amorpha, alfalfa, shrubs, grasses and other vegetation habitat. Conducive to soil and water conservation, but also ease the In the development of grass at the same time. Would also like to take the necessary measures to protect water and soil conservation projects, according to local conditions to build scale pit, ring ravine, anti-slope terrace, and embankments, reservoirs and even Gufang. The formation of three-dimensional soil and water conservation project network and multi-level biological systems. Play consolidation soil, slowing the velocity, increase infiltration, Han Xu water, drought and soil conservation and so on. In particular, both water terraces, both the role of water conservation, but should speed up the development. Flow south of the Weihe River in the cold and humid mountainous area is the area most important conservation area of Suwon, status Grassy slopes, mostly secondary forest after a bad slope vegetation,Converse chaussures, thin soil,uggs kopen, trampling intolerance, the use of improper soil and water can easily cause loss and debris flow hazards. Therefore, destruction of vegetation should be prohibited, the implementation of returning farmland to forest and grassland, restoration of natural vegetation. To prevent water recession, to ensure sustainable use of resources, adhere to prohibit the destruction of vegetation caused by man, resolutely check on steep slopes, land reclamation, excessive digging and the behavior of wild drug destruction of vegetation; has been cultivated for more than 25. Of cropland with the state policy of returning farmland to forest and pasture strongly messy down. (2) integrated activities management. Water first. Water development to adhere to the The full implementation of surface water, groundwater, rainwater, Promote the sustainable use of water resources. (I) the water diverting ecological engineering. Implementation of the project can fundamentally solve the Weihe River in northern l1 counties (cities) of the drought and water shortage problems. 80 000 h to improve the conditions of irrigation water, and establish a Along the urban and rural areas for the project may be sufficient to provide quality water and industrial water. Can effectively reduce soil erosion, improving ecological environment and promote regional ecological conditions improve. (2) reservoir control engineering. Southern tributary of the Weihe River is better Heyuan vegetation, water more abundant. Low river sediment, water quality is better, and narrow terrain. With favorable conditions to build a small reservoir. Recent planning and building of the Mount Lotus, shovel valley, mixed-inch Amoy, bottom of the cliff, green tiles Temple, home segment Gap, shizui other seven reservoirs, the reservoir regulation and storage capacity from the status quo Luk Keng 030 million raised to 1.22 billion zrf, runoff storage rate from less than 4% to 19%. Sichuan Plateau Valley to ease the industrial and agricultural and ecological water use conflicts. (3) {Dao control engineering. As soon as possible Weiyuan, Wei {Longxi counties 36km river can flow planning task to ensure that 1.35 million people, l0 bar channel, 2700hd farmland flood safety. Tributaries while Zhang, Longchuan River into the management plan, complete the task. Establish a complete flood control basin system to ensure flood safety. In connection with the construction of embankment, flood land use _ and j, the construction of fish ponds. Expand the fish water, development of fishery production, improve water yield. Some of the southern Rocky Mountain region of small tributary debris flow, should adhere to the Strengthen government functions, Mizoguchi alluvial fan in the debris flow, alluvial fan and debris flow slope angle of the settlements. Lok Man Sun Chuen combination of construction, relocated to safe areas; for other special lots, should be actively used for afforestation,Moncler prezzi, recovery of vegetation, build drainage pipes and drainage, stone and other measures to fight dam stopped, the plot to catch prevention, harm and loss of the debris flow is reduced to minimum. (4) rainwater harvest project. The majority of the Weihe River north of the Loess Plateau region. River Terrace sporadic distribution, both difficult to solve the water I cleanse works with the title, because of surface water, groundwater is extremely poor and difficult to develop small-scale irrigation, only a close connection with the construction of terraces, small watershed management, collect and store rainwater, supplemented by water injection furrow,tory burch reva, ridge membrane channel types, film culture, science and technology in water-saving irrigation and other efficient agricultural irrigation Rainwater Harvesting, Rainwater Harvesting 1 mu per capita farmland irrigation targets of stem
