Study On Data Fusion And Models Research In The Hardwood Resource With Hunan Province

This paper takes secondary forest precious indigenous tree species in South China as the research object, using the direct market approach, surrogate market approach and hypothetical market method for Research on the evaluation of the value, and From the narrow range of the system and summarizes the significance anddevelopment trend of efficient utilization.This paper establishes the evaluation system ofmeasuring a set of scientific, practical secondary forest precious indigenous tree species in South China, and the use of the measurement system, a quantitative evaluation on three kinds of Schima superba, Sassafras tzumu and Castanopsis sclerophylla. In this paper, study on high efficiency, according to the development direction of the wood industry, analyzed the development trend of secondary forest precious indigenous tree species in South China do.This article’s content is a part of the public welfare industry of the state forestry administration research projects:"Southern collective secondary forest tending and thinning and efficient use of technology research (The Item Number:201004032)." The main contents of this paper include the following aspects:(1) value evaluation of measurement system of the secondary forest precious indigenous tree species in South China:according to the actual conditions of the study area, combined withthe domestic and foreign research results, this research mainly from the direct economic value, environmental value, the value of social benefits and special precious value four aspects to evaluate. After a comprehensive analysis, this paper choose the forest products and forest by-products value, water conservation, soil conservation, carbon fixation and oxygen release, purifying atmosphere, accumulation of nutrients, bio diversity protection, provide employment value, cultural value and special precious value of ten indicators to comprehensive evaluation of the secondary forest precious local tree seed value benefit.(2) the study of evaluation of secondary forest precious indigenous tree species in South China:study area selected precious indigenous tree species Schima superba, Sassafras tzumu and Castanopsis sclerophylla as the object of study. Using the value measurement system, calculation value of three different species plots, threespecies of direct economic value, respectively:1152yuan,1325yuan,1500.4yuan; the total value of plots are as follows:4411.2yuan,5171yuan,4461.3yuan, the direct economic value of forest accounts for only total value sample1/4to1/3, the results accord with the general rule of the value evaluation of forest.(3) the paper from the narrow range of efficient use of precious indigenous tree speciesare discussed, analyzed and the future development trends of the secondary forest of native species of precious wood.
