【摘要】:本文以普格县为研究区,总结县域生产-生活-生态(简称“三生”)用地分类体系,探索“三生”空间优化方案。建立遥感影像解译标志,人工目视判读获取研究区1995年、2005年和2015年土地利用数据,并在此基础上构建区域“三生”用地空间分类体系,生成研究区“三生”用地空间数据集。基于ArcGIS和Fragstats软件平台,采用空间分析、定量分析、灰色模型预测和景观格局分析等方法,分层次多角度分析研究区“三生”空间分布特征,揭示“三生”用地时空演变规律,发现“三生”空间需求问题。结果表明:1)普格县“三生”用地空间分布和时空转换都深受地形地貌制约,生产和生活空间沿河谷呈“Y”字形分布;2)生产空间和生态空间存在时空对换趋势,即生产用地扩张所占用的生态空间在下一个研究时段又转还为生态空间;3)海拔3000m以下是生产和生活空间的优势分布区,在坡度6°-25°、地形起伏度30m以下、阳坡和半阳坡、道路和河流两侧生产和生活空间集聚,生态空间与之相反;4)政策因素对普格县三生用地的空间布局影响逐渐加深,随着生态文明建设提上日程,生态空间保护日渐得到重视。研究发现:1)农业生产空间生产量尚不能满足普格县人民自给自足,工业生产空间亟需转型与产业升级。2)交通是制约生活空间扩张的首要因素,脱贫攻坚仍是农村生活空间的首要任务。3)普格县作为国家重点生态功能区,其生态保护工作压力巨大。针对以上发现提出优化建议:农业生产以优质增产为重心,以自给自足为目标;工业生产以转型为核心,以集聚集群为途径;生活空间以交通、水利等设施建设为首要任务,以综合实施扶贫项目为重心,以挖掘乡镇潜力,建设特色城镇为发展方向;生态空间的发展要义是保障和增强生态用地的生态维护功能,坚守生态红线保护区,挖掘生态空间的经济潜能。
[Abstract]:Taking Puge County as the research area, this paper summarizes the land classification system of production, life and ecology in the county area, and explores the spatial optimization scheme of "Sansheng". The land use data in 1995, 2005 and 2015 were obtained by artificial visual interpretation of remote sensing images. On this basis, the spatial classification system of "Sansheng" land in the study area was constructed, and the spatial data set of "Sansheng" land in the research area was generated. Based on the software platform of ArcGIS and Fragstats, spatial analysis, quantitative analysis, grey model prediction and landscape pattern analysis are used to analyze the spatial distribution characteristics of "Sansheng" in the study area, and to reveal the space-time evolution law of "Sansheng" land. Discover "three life" space demand problem. The results show that: 1) the spatial distribution and space-time conversion of "Sansheng" land in Puge County are restricted by landform and geomorphology, and the production and living space is "Y" zigzag distribution along the river valley; 2) there is a trend of space-time exchange between production space and ecological space, that is, the ecological space occupied by the expansion of production land is converted to ecological space in the next research period; 3) below 3000m above sea level is the dominant distribution area of production and living space, with slope of 6 掳-25 掳, terrain fluctuation of less than 30 m, sunny slope and semi-sunny slope, production and living space on both sides of road and river, and ecological space is the opposite; 4) the influence of policy factors on the spatial distribution of Sansheng land in Puge County was gradually deepened. With the construction of ecological civilization on the agenda, ecological space protection was paid more and more attention. The results show that: 1) the production of agricultural production space can not satisfy the self-sufficiency of the people in Puge County, and the industrial production space needs to be transformed and upgraded urgently. 2) Traffic is the primary factor restricting the expansion of living space. Getting rid of poverty is still the primary task of rural living space. 3) as a national key ecological functional area, Puge County has a great pressure on ecological protection. In view of the above findings, the following suggestions are put forward: the focus of agricultural production is high quality and production increase, the goal is self-sufficiency, the core of industrial production is transformation, and the way of agglomeration is industrial production. The living space takes transportation, water conservancy and other facilities construction as the primary task, the comprehensive implementation of poverty alleviation projects as the focus, to tap the potential of towns and townships, and to build characteristic towns as the development direction; The key to the development of ecological space is to ensure and strengthen the ecological maintenance function of ecological land, adhere to the ecological red line reserve, and tap the economic potential of ecological space.
