The Research On The Dynamic Changes And Optimization Of "Production-living-ecological" Space In Western Sichuan Plateau

The Study on the Dynamic Changes and Optimization of "Production-Living-Ec-ological" Space in Western Sichuan Plateau—Take Luhuo County as an example,Not only important for the sustainable development of Luhuo County,And it is of great significance to the sustainable development of the entire plateau region of western Sichuan.So.this article selects Luhuo County as the research object.by Obtain remote sensing images for Lumen County in 1990,2000,2010 and 2015,Using ArcGis to interpret land data for four years,Reclassification based on land use type,Divide the production,living,and ecological space,referred to as the “Production-Living-EcoLog-ical” space.Acquiring the layout and dynamic changes of the "Production-Living-Ecol-ogical" space in Luhuo County.By analyzing the background characteristics of the “Production-Living-Ecological” space,Based on the natural and socio-economic environment of Luhuo County,Analyzed the layout of the "Production-Living-Ecologic-al" space in Luhuo County.and make a suggestion.The results show:(1)Grassland and woodland accounted for the highest proportion of Luhuo County in 2015,with 48.04% and 43.84% respectively.(2)In the production space,the grassland is the most widely distributed and is concentrated on the hills and slopes with an elevation of about 3800 m.It is a typical highland pastoral area.Affected by the topography,cultivated land is mainly distributed in the Muqu River and the Xianshui River Basin.The living space is mainly distributed along the “Y” river valleys and is mainly concentrated in Xindu Town,Muqu River and Xianshui River Basin.The elevation is 3052-34400 m,the slope of 0-20°,the undulation is less than 80 m,and the traffic is convenient.The distribution of ecological space is contrary to the living space and production space.(3)The spatial-temporal transformation of the "Production-Living-Ecological" space in Luhuo County is greatly affected by the terrain and rivers,and the conversion is most obvious;(4)The influence of policy factors on the layout and conversion of the “Production-Living-Ecological” space in Luhuo County is increasingly deepened,and the importance attached to the protection of the ecological environment is increasing.The study found:(1)The output and efficiency of the agricultural production space cannot meet the needs of the people of Luhuo County.The development of industrial production space requires the government's macro management.(2)Luhuo County needs the development of transportation to achieve poverty alleviation;(3)Ecological Environment Protection in Western Sichuan Plateau.Optimization suggestions:(1)Agricultural production space to increase production;Industry should increase investment in science and technology and realize industrialization.(2)The reasonable layout of residential areas,appropriate increase in roads;(3)Ecological space should stick to ecological red line protection areas,make rational use of ecological space,and create economic value.
