摘要

准确识别土地利用格局时空演变规律和轨迹特征

对科学推进该地区生态保护和社会经济高质量发展具有重要意义。采用1990年、2005年和2018年3期土地利用数据构建鄂西南地区土地利用变化轨迹序列

利用土地利用变化各项指数、弦图可视化、标准差椭圆方法

从地类总量变化特征、数量变化轨迹特征和空间变化轨迹特征3个方面开展

揭示近30年来鄂西南地区土地利用格局时空演变特征与变化趋势。结果表明: (1)土地利用总量变化稳定性特征明显。林地和耕地始终是研究区主要土地利用类型

耕地持续减少

建设用地持续增加

土地利用变化活跃但整体态势平缓。(2)土地利用格局数量变化轨迹主导性特征鲜明。1990—2005年以耕地和林地之间相互转换及林地的流出为主

2005—2018年以耕地、林地和草地之间的相互转换、建设用地的进一步扩张为主

整体上地类的变化表现为空间位置上的转移。2005—2018年比1990—2005年土地利用变化类型更多样

土地利用变化行为更活跃。(3)空间变化轨迹集聚性和分异性特征显著。2005—2018年综合土地利用动态变化强度更大。近30年来研究区土地利用格局变化重心、面积、方向和扩散趋势存在空间变化。研究成果为鄂西南地区土地利用研究和国土空间规划提供了参考依据。

Abstract

Accurate identification of the temporal and spatial evolution law and trajectory characteristics of land use pattern is of great significance to scientifically promote ecological protection and high-quality socio-economic development in the region. Three periods of land use data in 1990

2005 and 2018 were used to construct the trajectory sequence of land use change in the southwest Hubei. In order to reveal the spatial and temporal evolution characteristics and change trend of land use pattern in the southwest Hubei over the past 30 years

using various indices of land use change

chord diagram visualization and standard deviation ellipse methods

this study carried out from three aspects: total land use change characteristics

quantitative change trajectory characteristics and spatial change trajectory characteristics. The results showed that: (1) Stability characteristic of total land use change was obvious. Forestland and cultivated land were always been the main land use types in the study area. The area of cultivated land decreased continuously

while the area of built-up land increased continuously. The change of land use was active

but the overall trend was flat. (2) The dominant characteristics of the quantitative change trajectory of land use pattern were obvious. From 1990 to 2005

it was dominated by the mutual conversion between cultivated land and forestland and outflow of forestland. From 2005 to 2018

it was dominated by mutual conversion between cultivated land

forestland and grassland and further expansion of built-up land. On the whole

the change of land type was manifested in the transfer of spatial location. Land use change types were more diverse

and land use change behavior was more active in 2005—2018 than those in 1990—2005. (3) The spatial change trajectory was characterized by significant clustering and divergence. From 2005 to 2018

the dynamics change intensity of comprehensive land use was greater. There were spatial variations in the center of gravity

area

direction and diffusion trends of land use pattern change in the study area over the past 30 years. The results could provid a reference basis for land use research and territorial spatial planning in the southwest Hubei Province.
