【摘要】：土地资源是人类社会生存和发展的基础,具有稀缺性和不可再生性等特点。当前,土地利用动态变化研究是一个综合型的热点问题。云南省保山市隆阳区位于云贵高原,是我国西南部对外开放的门户。近十年来随着经济的迅速发展,该地区产业结构得到了深化调整。在上述背景下,研究土地利用格局变化规律对于隆阳区的持续发展具有十分重要的现实意义。本文综合运用土地利用综合指数模型、马尔科夫预测模型、主成分分析方法及GIS叠置分析等方法模型对隆阳区土地利用动态变化规律进行研究,最后基于WebGIS技术构建隆阳区土地利用动态分析查询系统。本文相关研究内容如下： 1、土地变化分析。本文对隆阳区2001年Landsat7和2013年landsat8两期遥感影像进行拼接、裁剪和解译,最后得到土地利用分类图。对比两期分类结果数据发现,同2001年相比,2013年隆阳区的建设用地、耕地面积有所增加,林草地及未利用地面积相对减小,水域面积整体变化不大。进一步对隆阳区土地利用进行时空变化分析可得,相较于2001年,2013年该地区建设用地增加26.45%,主要由林草地和耕地的转化而来；耕地面积减少1.13%,主要转化为建设用地；未利用地减少19.96%,主要转移去向为林草地。 2、土地利用程度分析。利用刘纪远先生提出的土地利用综合指数模型,从整体上对隆阳区土地利用程度进行评估分析可知：2001年全区土地利用程度综合指数为228.340,2013年为229.547,十二年间全区土地利用程度变化值为1.207,表明隆阳区的土地利用格局处于发展期。 3、土地利用预测。利用马尔科夫预测模型对2025年土地利用情况进行预测。结果表明,2025年全区建设用地增长21.357%,耕地减少1.13%,林草地减少0.62%,未利用地减少12.79%,水域面积增加2.73%；2025年土地利用综合指数为230.191,较2013年增长0.611,全区土地利用仍处于发展期。 4、驱动力分析。通过主成分分析得到隆阳区2001年到2013年土地利用格局变化的主要驱动因素为GDP、农业发展、消费品零售总额和城市化率。
[Abstract]:Land resources is the foundation of the survival and development of human society, has the characteristics of scarcity and non renewable. At present, the land use dynamic change is a hot issue in general. In Longyang District of Baoshan city in Yunnan province is located in the Yunnan Guizhou Plateau, Southwest China is opening up the door. Over the past ten years, with the rapid the development of economy, the industrial structure of the region has been deepening adjustment. In the background, for the sustainable development in Longyang District have the regular patterns of land use change research is of great practical significance. This paper uses the comprehensive index of land use model, Markov model, principal component analysis and GIS model analysis method for overlay study on the regularity of dynamic change of land use in Longyang District, based on the construction of Longyang District land use dynamic analysis query system WebGIS technology. In this paper, the relevant research contents are as follows:
1, land change analysis. In this paper the mosaic of Longyang District 2001 Landsat7 and 2013 landsat8 remote sensing image, cutting and interpretation, and finally get the land use classification map. Comparison of two data classification results found that compared with 2001, in 2013 the construction of Longyang District land, arable land area increased, grassland and unused land the relative decrease of water area changed little overall. Further to Longyang District land use spatial and temporal variation analysis, compared to 2001, 2013 in the area of construction land increased by 26.45%, mainly by the transformation of forest and grassland and arable land to 1.13%; reduce the area of arable land, mainly transformed into construction land; unused land decreased by 19.96%. The main transfer destination for forest and grassland.
2, the analysis of land use degree. The comprehensive index of land use model proposed by Mr. Liu Jiyuan, evaluate the analysis of land use degree in Longyang District on the whole: in 2001 the comprehensive index of land use degree for 228.3402013 years was 229.547, twelve years the land use change degree was 1.207, showed that Longyang District land use pattern at the stage of development.
3, land use prediction. To predict the situation of land use in 2025 by the Markoff prediction model. The results show that in 2025 the construction land increased by 21.357%, 1.13% reduction of cultivated land, forest and grassland decreased by 0.62%, unused land decreased by 12.79%, water area increased by 2.73%; in 2025, the comprehensive index of land use was 230.191, an increase of 0.611 compared to 2013, the region's land use is still in the development period.
4, analysis of the driving force. By principal component analysis from 2001 to 2013 the main driving Longyang District land use pattern change factor GDP, agricultural development, retail sales and city consumption rate.
