【摘要】：本文以普格縣為研究區(qū),總結(jié)縣域生產(chǎn)-生活-生態(tài)(簡稱“三生”)用地分類體系,探索“三生”空間優(yōu)化方案。建立遙感影像解譯標(biāo)志,人工目視判讀獲取研究區(qū)1995年、2005年和2015年土地利用數(shù)據(jù),并在此基礎(chǔ)上構(gòu)建區(qū)域“三生”用地空間分類體系,生成研究區(qū)“三生”用地空間數(shù)據(jù)集�；贏rcGIS和Fragstats軟件平臺,采用空間分析、定量分析、灰色模型預(yù)測和景觀格局分析等方法,分層次多角度分析研究區(qū)“三生”空間分布特征,揭示“三生”用地時空演變規(guī)律,發(fā)現(xiàn)“三生”空間需求問題。結(jié)果表明:1)普格縣“三生”用地空間分布和時空轉(zhuǎn)換都深受地形地貌制約,生產(chǎn)和生活空間沿河谷呈“Y”字形分布;2)生產(chǎn)空間和生態(tài)空間存在時空對換趨勢,即生產(chǎn)用地擴張所占用的生態(tài)空間在下一個研究時段又轉(zhuǎn)還為生態(tài)空間;3)海拔3000m以下是生產(chǎn)和生活空間的優(yōu)勢分布區(qū),在坡度6°-25°、地形起伏度30m以下、陽坡和半陽坡、道路和河流兩側(cè)生產(chǎn)和生活空間集聚,生態(tài)空間與之相反;4)政策因素對普格縣三生用地的空間布局影響逐漸加深,隨著生態(tài)文明建設(shè)提上日程,生態(tài)空間保護日漸得到重視。研究發(fā)現(xiàn):1)農(nóng)業(yè)生產(chǎn)空間生產(chǎn)量尚不能滿足普格縣人民自給自足,工業(yè)生產(chǎn)空間亟需轉(zhuǎn)型與產(chǎn)業(yè)升級。2)交通是制約生活空間擴張的首要因素,脫貧攻堅仍是農(nóng)村生活空間的首要任務(wù)。3)普格縣作為國家重點生態(tài)功能區(qū),其生態(tài)保護工作壓力巨大。針對以上發(fā)現(xiàn)提出優(yōu)化建議:農(nóng)業(yè)生產(chǎn)以優(yōu)質(zhì)增產(chǎn)為重心,以自給自足為目標(biāo);工業(yè)生產(chǎn)以轉(zhuǎn)型為核心,以集聚集群為途徑;生活空間以交通、水利等設(shè)施建設(shè)為首要任務(wù),以綜合實施扶貧項目為重心,以挖掘鄉(xiāng)鎮(zhèn)潛力,建設(shè)特色城鎮(zhèn)為發(fā)展方向;生態(tài)空間的發(fā)展要義是保障和增強生態(tài)用地的生態(tài)維護功能,堅守生態(tài)紅線保護區(qū),挖掘生態(tài)空間的經(jīng)濟潛能。
[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 擄-25 擄, 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.
