定量分析景观格局对土地利用变化的响应,可为区域实现空间高质量发展提供科学依据.以集生态脆弱、集中连片特殊困难、旅游资源丰富于一体的典型区域--湘西自治州为研究对象,基于2000、2005、2010、2015和2018年5期遥感影像数据,综合运用景观指数和普通最小二乘法等,定量分析区域土地利用和景观格局的时空演变规律,探讨土地利用变化对景观格局的影响,揭示人为活动影响下景观格局对土地利用变化的响应特征.研究结果表明:1)开发区和新城区建设等经济社会发展过程中土地利用发生显著变化,其主要特征为耕地和草地转化为
Abstract:
Quantifying the effects of land use on landscape pattern is of importance for providing scientific basis for high-quality spatial development. The Xiangxi Autonomous Prefecture in Hunan Province, which was characterized with fragile ecology, concentrated contiguous special poverty and rich in tourism resources, was chosen as the study object. Based on the remote sensing image data of 2000, 2005, 2010, 2015 and 2018, landscape indexes and ordinary least squares were used to study the temporal and spatial patterns of land use and landscape, to analysis the effects of land use on landscape, and to reveal the the response of landscape to land use changes. The following results were obtained: 1)During the economic and social development period, significant changes have been made in land use in the construction of the development zone and new urban districts, etc. One of the main features is that the arable lands and grasslands were turned into development lands. From 2000 to 2018, the area of the development land has increased by 79.46 km2, while the area of the cultivated land and grassland have decreased by 86.01 km2 and 4.6 km2 respectively. And little changes were noticed in water area and unused land. 2)The landscape pattern showed an increasing trend in fragmentation and a decreasing trend in aggregation degree. 3)Strong relationships between landscape pattern and land uses were observed. The expansion of development land increased both the fragmentation and heterogeneity of landscape pattern. 4)Economic development, ecological construction, and national strategy are the main cause of the continuous increasing of forest land and the optimization of landscape pattern. Coordinated optimization of space using and landscape will benefit the follow-up development.
