| 摘 要： | 通过多种方法分析大西安地区土地利用类型演变特征、空间变化特征及其影响因素，旨在为大西安地区土地利用优化发展提供科学基础。在GIS和RS技术的支持下，对区域1996年、2006年、2016年3期LANDSAT TM（OLI）遥感影像进行解译，采用土地利用转移矩阵和土地利用变化模型对大西安1996 年以来土地利用类型和土地覆被时空动态变化进行量化分析，结果表明：（1）
大西安近20 a来建设用地面积不断增加，耕地、林业用地面积总体减少，草地小幅增加，水域略有萎缩，各地类间相互转换频繁。（2） 土地利用综合程度较高且不断加强，土地利用结构趋于均衡。（3） 空间变化上，土地利用变化区域差异显著，建设用地、耕地、林业用地重心转移的速度呈现出先快后慢的阶段性特征。（4） 综合相关文献，大西安地区土地利用变化的驱动因素主要为政策因素。论文从时空变化角度首次提出大西安地区的土地利用演变规律，该结果可为大西安地区发展过程中的土地优化提供科学基础。

| Abstract: | The evolution,spatial variation,and influencing
factors of land use types in the greater Xi’an
area have been insufficiently quantified.In order to provide a scientific basis
for the optimal use and development of land in the
greater Xi’an area,we analyzed and interpreted regional remote sensing images
from the Landsat Thematic Mapper and Operational Land Imager from 1996,2006,and
2016.We adopted a land use transfer matrix and land use change model to conduct
quantitative analysis of the spatial and temporal changes in land use and land
cover since 1996.We supported these tools with GIS and RS technologies.We found
that the area of developed land in the greater Xi’an
area,Shaanxi Province,China has increased over the past 20 years,while
cultivated and forested land has decreased.Grassland has increased
slightly,while the water area has shrunk slightly.We noted frequent
classification changes.The comprehensive degree of land use was high and
constantly strengthened over time,and the land use structure tended to be
balanced.We identified significant regional differences in land use change,and
the transfer speeds of the centers of gravity of construction land,arable
land,and forestry land shows the characteristics of the stages of speed before
slowness.The driving factors of land use change in the
greater Xi’an area were mainly policy factors.This paper proposes the land use
revolution rule of the Great Xi’an
area for the first time from the angle of time and space change.Our results
should provide a scientific basis for land use optimization as the
greater Xi’an area continues to develop and grow. |
