Research Of Technology Of Comprehensive Harnessing Of Ecological Project Of High-efficient Water And Soil Conservation

With the implementation of Taian City Taian Dawen River Basin Project Area Small Watershed Management works to Xujiaqiao Timorese and Daiyue district JINDOUSHAN Xintai City,and other key watershed for the study,the study area in the investigation of the natural conditions,such as socio-economic conditions on the basis of soil conservation and ecological management at home and abroad from new technologies and new theory, comprehensive analysis of the status of governance of small watershed areas, use of ecology and systems engineering principles of sustainable development to follow the law,uphold the engineering,biological and farming measures on the principle of combining,the continued development of the watershed study, come to the following conclusions:(1)Application Gully section of information entropy analysis,principal component analysis,cluster analysis,the proposed study area and gully erosion and development of the rules and characteristics,and gully erosion theory and its method of classification of a new sound and supplementary. Gully erosion from the study area generally divided into the early,"V"-type development ditch,in order to put back the main erosion,the medium-term "U"-type expansion ditch,traceability erosion,incised erosion,erosion at the same time dramatic development side,the late","Ditch three types of corrosion,erosion channel upstream of the 3-D there are still,gully erosion of the middle and lower reaches has been basically stopped,the channel stabilizing.(2) Raised typical small watershed different types Channel's "three-dimensional cascade" Technology Integration Management and Development model.Namely,the initial "V" groove type development "trough slope,Taiwan,ladders,channel locks,cut,siltation" mode;The medium-term "U"-type expansion of the Ditch,"the slope forest,fruit,trench,the channel bar,with,for a" pattern;Later,""corrosion-ditch "fruit slope,animal husbandry,tent-channel letters,planting,agricultural "mode.Cascade different development model and configuration management technology,similar regions in China with important promotional value. (3) Establishment of a typical small watershed efficient cultivation of water-saving irrigation technology integration model.Rational use of water resources through technical system,water-saving technology system,and the management of water-saving system,improving agronomic measures for the effective use of existing water resources,increase the use of water resources of various degrees,reducing the water in the course of transmission loss and inhibit transpiration farmland invalid evaporation,reduce surface units plot farmland net water consumption,improving irrigation efficiency,increase crop productivity,achieve high yield and high efficiency of agricultural production.(4)In the study area through various different implementation of the Small Watershed Ecological Engineering comprehensive management of water and soil conservation measures,and in the entire study area Dawen River widely used,the development of a total area of governance 403.79 km2,the study area,storage capacity reached 60.4582 million m3,water storage efficiency increased by 24.69%;the new security measures soil amounted to 493,400 t, the study area,and soil reaches 2421400 t,and soil efficiency increased 20.38%.Through projects will greatly improve the ecological environment of the study area,and promote the sustainable development of regional economy.
