【摘要】：對(duì)新疆未利用土地進(jìn)行合理分區(qū)與開(kāi)發(fā),不僅可以高效利用新疆寶貴的土地資源,而且還能夠改善新疆的生態(tài)環(huán)境、實(shí)現(xiàn)新疆未利用土地的潛在價(jià)值。本文結(jié)合可持續(xù)發(fā)展理論與水土資源承載力、系統(tǒng)論與水土資源耦合關(guān)系、比較優(yōu)勢(shì)理論,區(qū)位理論的指導(dǎo)下,借助ArcGIS空間分析、數(shù)理統(tǒng)計(jì)等軟件平臺(tái),綜合分析地貌、經(jīng)濟(jì)區(qū)位等對(duì)新疆土地格局及其變化的影響,對(duì)新疆未利用土地進(jìn)行分級(jí)、評(píng)價(jià)與動(dòng)態(tài)變化模擬。主要研究結(jié)果如下:1:首先界定本文研究的“未利用土地”,再?gòu)摹拔蠢�用土地”的自然屬性角度出發(fā),采用小波分析構(gòu)造新疆各區(qū)域氣溫、降水的分布圖;以新疆水土資源綜合承載力及耦合情況及各縣(市)級(jí)區(qū)域未利用土地面積為分析數(shù)據(jù),通過(guò)FCM與競(jìng)爭(zhēng)型神經(jīng)網(wǎng)絡(luò)模型對(duì)縣級(jí)區(qū)域未利用土地情況進(jìn)行聚類(lèi)分級(jí)與結(jié)果修正,其中選擇五類(lèi)指標(biāo)聚類(lèi)中心作為最佳未利用土地分區(qū)聚類(lèi)指標(biāo),最終得到新疆地區(qū)未利用土地類(lèi)型分類(lèi)后的各指標(biāo)等級(jí)結(jié)果表。結(jié)果顯示一級(jí)的未利用土地中難開(kāi)發(fā)的沙地與鹽堿地較少,而有利于開(kāi)發(fā)的荒草地與沼澤地較多;二級(jí)和三級(jí)的未利用土地中裸地占有較大比例;四級(jí)和五級(jí)以沙地為主。2:通過(guò)主成分分析和熵值法分析方法的融合,以新疆歷年統(tǒng)計(jì)年鑒數(shù)據(jù)及土地利用數(shù)據(jù)為研究數(shù)據(jù),以優(yōu)先選擇已利用耕地牧地綜合狀況較好、地區(qū)綜合情況有利于宜耕宜牧未利用土地開(kāi)發(fā)為目的構(gòu)建以縣(市)為評(píng)價(jià)單元的評(píng)價(jià)體系,得出新疆未利用土地宜耕地、宜牧的空間分布結(jié)果,由空間分布圖可以看出,宜耕宜牧地主要集中分布在新疆的北部、中部及西南部區(qū)域。為了更好地對(duì)未利用地可開(kāi)發(fā)程度進(jìn)行分析,建立了基于FCM模糊分類(lèi)中心和更為有效的競(jìng)爭(zhēng)型神經(jīng)網(wǎng)絡(luò)的分類(lèi)中心為依據(jù)的模糊綜合識(shí)別模型,由所得結(jié)果的可開(kāi)發(fā)程度等級(jí)空間分布可以得出,一級(jí)分類(lèi)占有新疆絕大地方,分布于新疆中部、西南部和北部。二級(jí)分類(lèi)主要分布在新疆北部和西部邊緣地帶。然而新疆的西南地區(qū)以三級(jí)和四級(jí)分類(lèi)為主,該區(qū)域新疆西南部年降水量比較少,且主要是南疆盆地地形為主。五級(jí)分類(lèi)的空間分布屬于新疆的高山冰川地帶,可利用程度極低。并對(duì)霍城縣進(jìn)行縣級(jí)未利用土地評(píng)價(jià),細(xì)化不同尺度的未利用土地評(píng)價(jià)指標(biāo),對(duì)未利用土地進(jìn)行分級(jí)。3:本文最終通過(guò)CLUE-S與Logistic模型模擬新疆全區(qū)的未來(lái)土地利用變化情況。其中針對(duì)未利用土地的開(kāi)發(fā)情況,在整個(gè)模擬過(guò)程中,未利用土地之間限制為不能相互變更,且其它非未利用土地也無(wú)法變更為未利用土地。從結(jié)果可以看出荒草地的變更量最大,其次是裸土地,之后依次為鹽堿地、沙地和沼澤地。該數(shù)據(jù)也進(jìn)一步說(shuō)明未利用土地的變更和規(guī)劃利用是土地類(lèi)型本身特征、社會(huì)經(jīng)濟(jì)發(fā)展的要求以及生態(tài)環(huán)境因素綜合作用的結(jié)果。
[Abstract]:The rational zoning and development of unused land in Xinjiang can not only efficiently utilize the valuable land resources in Xinjiang, but also improve the ecological environment of Xinjiang and realize the potential value of unused land in Xinjiang.Under the guidance of the theory of sustainable development and the carrying capacity of soil and water resources, the coupling relationship between system theory and soil and water resources, the theory of comparative advantage and the theory of location, the geomorphology is comprehensively analyzed with the help of ArcGIS spatial analysis, mathematical statistics and other software platforms.The influence of economic zone on the land pattern and its change in Xinjiang is analyzed. The unused land in Xinjiang is classified, evaluated and simulated dynamically.The main research results are as follows: firstly, the "unused land" studied in this paper is defined, and then the distribution map of temperature and precipitation in Xinjiang is constructed by wavelet analysis from the natural attribute of "unused land".Taking the comprehensive carrying capacity and coupling situation of water and soil resources in Xinjiang and the unused land area of each county (city) level as the analysis data, the paper classifies and corrects the unused land situation of county level area by FCM and competitive neural network model.The cluster center of five types of indicators is selected as the best cluster index of unused land zoning, and finally the result table of each index grade after classification of unused land type in Xinjiang is obtained.The results showed that the undeveloped sandy land and saline-alkali land were less in the first class of unused land, while the barren grassland and marsh land were more favorable for exploitation, and the bare land occupied a large proportion of the unused land in the second and third grade.Through the combination of principal component analysis (PCA) and entropy analysis method, taking the statistical yearbook data and land use data of Xinjiang over the years as the research data, the comprehensive condition of the preferentially selected cultivated land and pastures is better.The comprehensive situation of the region is conducive to the construction of the evaluation system with county (city) as the evaluation unit for the purpose of land exploitation of suitable ploughing and grazing, and the results of spatial distribution of the unused arable land and suitable pasturage in Xinjiang can be seen from the spatial distribution map.Suitable farming and grazing land are mainly distributed in the northern, central and southwest regions of Xinjiang.In order to better analyze the degree of exploitation of unused land, a fuzzy comprehensive recognition model based on FCM fuzzy classification center and more effective competitive neural network is established.It can be concluded from the spatial distribution of the degree of exploitation of the obtained results that the primary classification occupies the vast majority of Xinjiang, and is distributed in the central, southwest and northern parts of Xinjiang.The secondary classification is mainly distributed in the northern and western margin of Xinjiang.However, the southwest of Xinjiang is mainly classified into three and four classes. The annual precipitation in the southwest of Xinjiang is relatively small, and it is mainly the topography of the southern Xinjiang basin.The spatial distribution of the five-level classification belongs to the alpine glacier zone of Xinjiang, and its availability is very low.The evaluation of unused land at county level in Huocheng County was carried out to refine the evaluation indexes of unused land on different scales and to grade unused land. 3. Finally, this paper simulated the future land use change in Xinjiang by CLUE-S and Logistic models.According to the development of unused land, in the whole simulation process, the unused land is limited to not changing each other, and other unused land can not be changed to unused land.It can be seen from the results that the change of wasteland is the largest, followed by bare land, followed by saline-alkali land, sandy land and marsh land.The data also further shows that the change and planning of unused land is the result of the characteristics of land types, the requirements of social and economic development and the comprehensive effects of ecological and environmental factors.
