Study On Forestry Landscape Ecological Planning Of The Low-slope Hilly Based On GIS

As the important ecological security barrier in the central of China,Dabie mountain is the key areas of national poverty alleviation and development.As the various types of construction and development supplementary land resources,the low-slope hilly region is very significant for economic and social development.In order to exploit and utilize the low-slope hilly region resources reasonably under the premise of ecological environment protection and explore the new model of comprehensive utilization for the low-slope hilly region,Promoting industrial transformation and upgrading,transformating the model of economic development.This paper takes Susong County as an example,which based on SPOT5 images based high resolution remote sensing images,land use survey data in2011,social and economic data of Susong County,DEM digital elevation data,and other achievements as the basic data,finished the resources investigation of low-slope hilly region under the the support of GIS technology and ERDAS software.Then with the help of the analytic hierarchy process(ahp),select the correlation factor as the basic factor,establish index system,construct evaluation model,to make suitability evaluation of development and utilization for low-slope hilly land.On the basis of evaluation before,by using the theory of landscape ecology,the present situation of landscape pattern is analyzed.Combined with the terrain,topography and ecological landscape features,to complete the forest landscape ecological planning and designed.The research results were as follows:?The total area of low-slope hilly region resources is 118133.64 ha,which accounted for 49.84% of the total area of the county,from what we can see the total area of low-slope hilly region resources is very abundant,which have great development potential.The area of low-slope hilly region resources which can be exploited and utilized directly is 1501.03 ha,which accounted for 1.27% of the total area of low-slope hilly region resources of the county.?The suitability evaluation result shows that the best way to use low-slope hilly land is to use it as woodland.The area for development and utilization of low-slope hilly land available in Susong County's back-up resources is 134.64 ha?42.18 ha?442.50 ha ? 861.89 ha and 19.82 ha,suiting best for building,farming,gardening,forestry as well as unfavorable development,which respectively accounted for 8.97%,2.81%,29.48%,57.42% and 1.32% of the total reserve resources for the development and utilization of low-slope hilly land.?Analysis result of the current situation of landscape pattern in planning study area show that,firstly,the matrix landscape of the whole study area is the landscape of the woodland,in which landscape index of different landscape types have relatively large differences.Secondly,residential land and garden plot landscape connectivity index is smaller,landscape fragmentation is relatively high.Thirdly,the landscape of residential land,other land,garden plot and waters scattered around Hexi mountain,at the foot of the mountain distribute cultivated land,which belong to the lower area,showing a continuous distribution;The last,The middle of the research area is occupied by the forest land,which is in a large area of continuous and uniform distribution,and the surrounding is waters and traffic land,which shows that compared with the middle of the study area,the terrain is relatively slow,and is suitable for the landscape distribution of the residential land,cultivated land,garden and so on.?Forestry Landscape Ecological Planning in the study area is mainly based on forestry,including forest protection area,road protection forest zone,river protection forest zone and park greening area.In addition,has planned ecological agriculture area,ecological economic development zone,and urban construction area.In the middle of the study area planning the forest protection zone while along Shanghai Chongqing Expressway and 105 national highway planning two highway protection forest,along Shahe river planning protection forest,in the north of the urban construction zone,Shanghai Chongqing Expressway to the East,and the west of Shahe river,planning the park green zone,which located in the triangle zone.In eastern part of the mountain planning the eco-agricultural area,and the urban construction area planning in the North West of the river,on both sides of the 105 National highway.
