中文摘要	【目的】揭示喀斯特石漠化治理区景观格局演变及驱动因素,为优化示范区土地景观格局、石漠化治理以及区域可持续发展提供参考依据。【方法】以典型喀斯特高原毕节市撒拉溪示范区为研究对象,选取2005、2010年ETM和2015年OLI的遥感影像,采用3S技术与景观指数分析方法,研究其景观格局及其驱动因素。【结果】撒拉溪示范区主体景观是耕地,其次是灌木林地;景观转移变化主要表现为耕地向林草地和建设用地转化,2010年,分别占耕地转出量的73 .31 %和24.75 %;至2015年,分别占79.80 %和19.99 %;景观类型水平上,耕地、有林地和灌木林地破碎度不断加大,草地和建设用地破碎度先增大后减小趋势,除未利用地外,景观斑块形状均趋于复杂化;景观整体水平上,近10年示范区景观向破碎化、复杂化、离散化和均匀化方向发展。【结论】石漠化治理工程的实施、城镇化建设及土地撂荒是导致景观格局变化的主要因素。
英文摘要	【Objective】The present paper aimed to reveal the landscape pattern evolution and driving factors of karst rocky desertification area, and provide a reference for optimizing the land landscape pattern,rocky desertification control and regional sustainable development in the demonstration area.【Method】Taking the typical Karst Plateau Bijie Salaxi demonstration area as the research object,the remote sensing images of three key time periods were selected,including ETM in 2005,2010 and OLI in 2015.3S technology and landscape index analysis method were employed to study landscape pattern and the driving factors.【Result】The main landscape of the study area was cultivated land, followed by shrub forest. The changes of landscape transfer were mainly manifested in the transformation from cultivated land to forest,grassland and construction land,which accounted for 73.31 % and 24.75 % of the cultivated land transfer respectively in 2010; By 2015,they accounted for 79.80 % and 19.99 % respectively. At the landscape type level,the fragmentation degree of cultivated land,forestland and shrub land was increasing,and the fragmentation degree of grassland and construction land increased first and then decreased. Except for the unused land,the landscape patch shape tended to be complicated. In the overall level of the landscape,the landscape of demonstration area had developed in the direction of fragmentation,complexity,discretization and homogenization in the last 10 years.【Conclusion】The implementation of rocky desertification control project,urbanization construction and land abandonment were the main factors leading to the change of landscape pattern.
