Evaluation Of Forest Ecosystem Nature Reserves To Protect The Value Of Jangxi Province

In the nature reserve system of Jiangxi province,forest ecological types of naturereserves which are numerous,wide and significative,are the main body of the naturereserve construction in our province. By investigating,collecting literature,consultingand other forms,the paper collected expedition reports and overall planning of forestecology and related materials of29forest ecological types of nature reserves at theprovincial level.With the analytic hierarchy process (AHP),expert consultationmethod, the quarterback method and parameter estimate allelic research methods,thepaper builds the nature reserve protection value evaluation index system of forestecological type above the provincial level and gets a forest ecosystem nature reservesto protect the value of the results. At the same time,by using GIS technology andArcGIS software,this paper gets the space distribution of forest ecological types ofnature reserves at the provincial level,and discusses from the distribution offorests,cities elaborate multi-angle distribution.By rearching the value and spacedistribution of the forest ecological types of nature reserves at the provincial level,this paper aims to providing a theoretical basis and technical support for the protectivevalue of nature reserves,science promotion, priorities,major management and spatialdistribution of the nature reserves.The main research results are as follows:(1) Combining the expert consultation and AHP,the paper constructs Jiangxiprovincial Forest Protection and Nature Reserves value evaluation system andcalculate the weight coefficients corresponding indicators of the system.The systemincludes a total of three levels of19indicators,the system layers are indicators ofdiversity,rarity index,representative indicators of natural indicators,social indicatorsand economic value of the area adaptability,the indicator layer comprises a number ofvegetation types,the number of higher plants,terrestrial(spine)and other animalspecies.(2) The system collects29provincial-level nature reserves and above the basic data toconstruct a set of basic database Jiangxi provincial level and above the forestecosystem nature reserves.(3) The remote sensing image Jiangxi Province (TM) interprets the data,the province’sadministrative map,the province’s forest ecosystem nature reserves distribution map for overlay analysis,the results showed that: the spatial distribution of the province’snature reserves imbalance,Ganzhou,Jiujiang two City,the number of protectedareas,the density of the larger and smaller Yingtan,Xinyu equal density,nature reservesdistribution is consistent with the basic advantages of the province’s forestvegetation,but in southeast JiangXi natural geographical areas and in hilly areas Ganyu mountain vacancy protected areas.(4) Using parametric analysis,combined with conservation value forest ecosystem sortthe results and the province spatial layout features nature reserves,WuMei mountainand other five provincial nature reserves qualify as a national nature reserve as soonas possible,The Qiyun Mountain National Nature Reserve and other five protectedareas as a priority construction proposals.
