Analysis Of Forest Landscape Pattern And Forest Management Suggestions In RongXian Based On GIS

With human social and economic development,and production activities through different land use patterns continue to affect the environment,so that land use increasingly complex and strained,disrupt and change the pattern,which leads to the global environment and climate change.Therefore,to explore and observe land use,especially in the study areas of forest landscape pattern,can helps humans understand land use,improves the ecological environment,reasonablily produces ecological benefits of maximum efficiency,improve the human living environment.This paper is part of the "Rongxian Forest Resource Planning Survey" project to Sichuan Zigong City Rongxian,the use of GIS and other advanced technology,through fusion,band selection and reasonable integrated local topography image data and manual interpretation feature attributes,to land use vector data and raster data Rongxian study area,and divide the land use classification based on attributes of landscape pattern analysis software for the principal component analysis of the study area,so as to explore the area of sustainable development of a scientific basis.The main conclusions are:(1)In this study,using SPOT 7 satellite image information in 2013 as a data source which sensor receives,compared with ETM + multi-band characteristics of data,select one of the beneficial band data fusion experiment.(2)When considering a variety of fusion Fusion method and determine the best means of integration,ultimately determine the use IHS transform,SFIM transform and principal component transform image processing in the study area,so that disadvantages of each method of transformation can be mutually complemented,give full play to the advantages of making,ease of using and extraction.(3)In terms of selecting bands,using OIF index calculation method to analyze band that selected from SPOT 7 satellite sensor received,in order to make use the naked eye can achieve the best results.(4)By Fragstats landscape analysis software,it can be learned that the land use types in the study area CA,TA,PLAND,NP,LPI,MPS,MSI,MNN,ED,PAFRAC.It concludes that 992,217.82 hectares of arable land,that accounting for 57.53%of the total area of the landscape,Rongxian woodland area is 55222.73 hectares,accounting for 34.54%of landscape area,which is the second type is the subject of landscape in Rongxian.(5)In the study area woodland gathered high,the type of structure is single,block distribution have a certain degree of fragmentation,woodland areas are small,patches scattered,low aggregation,accounted for less than 1%of the entire landscape area Rongxian.Fragmentation of shrubs is high,geographical distribution is more concentrated,mostly grow in hilly terrain,but the average plaque area is small,it has not yet formed a considerable scale.Construction land area accounts for the small size of the total landscape,water distribution is far away from each other.(6)According to the results of landscape to forest management,put forward specific methods of optimization of woodland,including the rational use of terrain,to strengthen the introduction and cultivation of forest land to construction,adhere to the woodland plant species diversity as the principle of transformation measures to strengthen small forest patch connectivity building and determine ownership of forest land proposed and other methods of Rongxian 2013 landscape patterns and forest conservation to propose a solution.
