Different Study Of Mechanism That Blackland Degenerated In Yu Shu County Jilin Province

It is a world environmental problem that the black soil degradates .that three major blacksoil area of the world are faceing are that black soil is degradating in the district at present. Itinvolves the natural factors and involves the interference of the human factosr too. And causeblack soil constantly degradated,to the problem of black soil research was considerd from thecomprehensive factor in the past , degradation didn′t had well connection betweenphenomenon and mechanism, From come , studying black soil degradate problem withdifferent angle that study in the past this text, Study relation of black soil degradatemechanism and black soil degradate characteristic。Through considering synthetically, Choose the research area that the elm city of JilinProvince degradates as the black soil, Mainly considering the varied topographical groundform structure exists promptly in this area, There are the characteristics of degradating blacksoil of many types at the same time。This literary grace carries on research by differentmeans,Mainly analyze the integrated environment of the whole research district by GIStechnology, Carry on the statistical analysis of variance to the data by SPSS 11.5 software,Analyze , should study district different area, different black soil degradate difference andchange of characteristic mechanism display,Prove to analyze to the result of study , it is inconformity with actual conditions to obtain the research results by on-the-spot investigation。We Can judge the difference between mechanisms that the black soil degradates throughdifferent characteristics.Herein data gather , measure method and method of statistical analysis of materials byactual observation , laboratory routine mainly,Measured by every index of data to black soil,physical property and content of chemical element of the black soil are monitored。UtilizedTM remote sensing data of interpreting of image at the same time , get soil , vegetation ,hydrology , features of terrain to study district geographical key element data。Finally , studythrough statistical data district economy and land data of production capacity ,etc. offerd forresearch work science reasonable data support.Draw the following conclusions by studying us:1 Black soil characteristic of degradating of wind erosion The characteristic of degenerating of wind erosion is mainly the reducing of the physicalproperty of the body of soil and on the decline of production capacity, It is mainly that thebody structure of soil is incomplete Layers of thickness become thin organic content reduce ,soil humus layer become thin and plough sole shallow.。The view structure is shown that thevegetation is covered degree low, the soil presents phenomena of degradating such as thebroken Beijing opera ,etc..。2 Black soil characteristic of degradating of water erosionMain characteristic that water erosion degradate to display unit weight in soil increaseobviously , soil body appear board form , penetrating bad total hole degree of soil diminish.。Chemical property of soil demonstrate obvious characteristic too at the same time, havequick-acting N mainly, P content reduce in same regional content the sudden changephenomenon takes placing. The whole N content reduces to some extent. Standard that thewhole P is close to the normal black soil and degradate3 Characteristic of degradating of artificial disturbanceBlack soil artificial disturbance lead to the fact main characteristic displayed to degradatewhether biological circulation, district of black soil, is destroy, lead to the fact, land decline ofproduction capacity, organic matter person who reduce increase, produce/ throw diminishs,the ecosystem is destroyed, the soil is increased by serious pollution soil toxicity Physicalstructure of land shows as organic content reduce , wither junk content diminishscharacteristic。Farmland regional plough sole obvious suddenly change, soil body divide layerobviously .Finally , degradate through analysis result of thesis , to different black soil and that blacksoil degradating mechanism produced degradate in the area, put forward different black soildegradating, preventing a, curing and protective measures , The purpose is to realize theland resource is developed with people's economic growth in harmony, realize resources andhuman sustainablely development.
