Hills Soil Sort Research Of The Southeast Of Urumqi And Afforesting Suitable Foring Appraisal

Taxonomy of soil is the important sign of the scientific development level of the national soil, because soil classify of any rank has condensed the result that the system study to a series of soil property , soil developing and procession. It make soil managing and utilizing the basic materials of planning, soil information technology ,"digital soil"etc front main content that discipline study nowadays. It is a common language which carries on academic exchange and main media. The common understanding of domestic and international agrology experts nowadays is needed badly to set up soil terms and soil's cover world database. It is a front field of current discipline development to study soil properties and make a variation on different yardstick. This research selected and tracked domestic and international discipline development trends to make systemic sort research to the southeast hills soil in Urumqi and carry on suitable sexology appraise. At last, the research has made the following main achievements:1. Make investigations on main district soil type and its distribution character, obtaining specific and accurate soil section physical and chemical property materials. The studying area distributes brown calcic soil, Entisols, Meadow soil and soil of grassy marshland .By determining the qualitative and quota method combining together to carry on the sort of soil research and obtain these types of soil space distribution and the distribution area. We have worked out the distribution map of soil type (1: 10000) and the distribution map of the thickness of effective soil layer of soil (1: 10000) which can offer very reliable ocular strong materials and information for the fact that the regional land is utilized and planned.2. Propose the originally regional land resource suitable to the evaluation index system which has the important academic value and appraisal value of the using. According to the local ecological condition and setting up terms condition, analyzing a series of soil properties and obstacle factors, for instance the thickness of soil layer, gravel content, the salt makes up, salt content and the accumulating salt associating with burying the depth etc., All these above combine the topography , hydrology condition and corroding the intensity etc. . We also have systematic valued on the land utilized, which have offered solid scientific basis for this district vegetation, afforestation and beautification project.3. Associated soil categorise system with the soil adaptable valuation system, we have given the soil sort research for the new meaning. That has reflected the innovation of the research thought and theory concept.According to the goal of vegetation construction. We carry on suitable research of determining the nature of intensity and quantitatively analyze obstacle factors one by one.This research has further enriched the categorised research of soil and basic content of soil database establishment, reflecting the important academic thought; at the same time it has also offered scientific basis for the green land construction project of the wasteland hills of the southeast Urumqi and vegetation care.
