| 摘要: |
| 为了解山江海过渡性国土空间景观格局指数和人为干扰度的变化特征，以具有山江海过渡性特征的桂西南喀斯特-北部湾地区为研究对象，利用2000年、2010年和2020年GlobeLand30数据，基于移动窗口法分析研究区景观格局指数和人为干扰度的时空差异。结果表明：（1）景观格局随时间发生明显变化，景观指数呈现不同变化规律；（2） 2000-2020年研究区景观自西北向东南破碎化程度逐渐减弱，西北部的斑块形状最复杂且不规则，景观连通性变化最明显的是西北部，景观类型呈均衡化趋势分布，景观异质性增强；（3）研究区人为干扰度逐年增强，呈中部高、四周低，由中部向四周蔓延减弱的空间格局，各景观指数与人为干扰度有不同的相关性。本研究结果可为研究区景观格局的优化和可持续发展提供参考依据。 |

| Abstract: |
| In order to understand the change characteristics of landscape pattern index and human disturbance degree of the transitional land between mountains,rivers and seas,the karst-Beibu Gulf region in southwest Guangxi with the transitional characteristics of the mountains,rivers and seas was taken as the research object.Using the GlobeLand 30 data in 2000,2010 and 2020,the temporal and spatial differences of landscape pattern index and human disturbance degree in the study area were analyzed based on the moving window method.The results showed that: (1) The landscape pattern changed significantly with time,and the landscape index changed differently.(2) From 2000 to 2020,the fragmentation degree of landscape in the study area gradually weakened from northwest to southeast.The morphology of patches in the northwest was the most complex and irregular.The most obvious change in landscape connectivity was in the northwest.Landscape types showed a trend of equalization and landscape heterogeneity increased.(3) The degree of human disturbance in the study area was increasing year by year.There was a spatial pattern of high in the middle and low in the surrounding area,and the spread from the middle to the surrounding area was weakened.Each landscape index had different correlations with the degree of human disturbance.The results of this study can provide references for optimizing the landscape pattern and promoting sustainable development in the study area. |
