【摘要】：我国西南地区地形地貌复杂,生态系统多样,生物多样性丰富,是研究地表复杂过程与生态系统演变规律的关键区域,也是我国重要的生态屏障区。但是同时该区域环境复杂、生态脆弱、灾害严重,在全球气候变化背景下,人类活动和经济发展导致该区域的生态环境问题比较突出,同时区域的社会经济发展地域分异大。突出表现在区域生态系统服务功能受损,区域生态安全水平降低。如何维护区域生态安全具有重要意义。针对生态安全问题,我国已开展生态区划、生态功能区划和生态红线等工作,但在生态安全格局的形成机制、与生态系统服务耦合关系、人类活动和气候变化对生态安全格局影响及其适应、区域社会经济可持续发展等方面需要加强深入研究,在我国西南地区的开展研究西南生态安全格局形成机制及演变机理具有典型性、代表性与紧迫性。
[Abstract]:The topography and geomorphology of southwest China are complex, the ecosystem is diverse and the biodiversity is rich. It is the key area to study the complex process of the surface and the law of the evolution of the ecosystem, and it is also an important ecological barrier area of our country, but the environment of the region is complex at the same time. In the context of global climate change, human activities and economic development have led to serious ecological and environmental problems in the region. At the same time, the regional social and economic development has great regional differentiation. The prominent manifestation is that the service function of regional ecosystem is damaged, the level of regional ecological security is reduced. How to maintain the regional ecological security is of great significance. Ecological regionalization, ecological functional regionalization and ecological red line have been carried out in China. However, the formation mechanism of ecological security pattern, the coupling relationship with ecosystem services, the influence of human activities and climate change on ecological security pattern and their adaptation to ecological security pattern have been carried out in China. It is necessary to further study the sustainable development of regional social economy. The research on the formation mechanism and evolution mechanism of ecological security pattern in southwest China is typical, representative and urgent.
