摘要
受人类活动和快速城市化的影响,深圳市景观生态安全面临严峻挑战,有必要对深圳市景观生态安全进行研究。本文以景观干扰度和景观脆弱度来构建景观结构指数,以生态系统服务价值和生态弹性度来表征景观功能,以景观结构和景观功能的动态变化来表征景观动态,在景观结构、功能和动态变化的基础上,建立深圳市景观生态安全评价指标体系。得到主要结论:1)深圳市区域内景观生态安全状况有明显差异,总体上看,深圳市景观生态安全分布大致呈现西低东高的分布格局,高生态安全区主要位于深圳市东部大鹏新区、盐田区、罗湖区内,低生态安全区主要位于深圳市西部广泛地区;2)宝安区、福田区、光明新区、龙岗区、龙华新区、南山区景观生态安全状况相对较差,大鹏新区、罗湖区、坪山新区、盐田区生态安全状况相对较好;3)将深圳市景观生态安全空间分异图和基本生态控制线进行叠加,生态控制线内较低和低景观生态安全区域,主要位于于龙岗区、南山区和光明新区内。
Affected by human activities and rapid urbanization, landscape ecological security of Shenzhen City is facing serious chal- lenges, so it is important to study the landscape ecological security of Shenzhen City. Based on landscape structure, landscape func- tion, and the dynamic changes of the landscape structure and landscape function, this paper built the index system, where the land- scape structure index was built on landscape disturbance degree and vulnerability, and the landscape function index was built on eco- system services value and ecological elastic. The results showed that： （ 1 ） There is a significant difference on the spatial pattern of landscape ecological security in Shenzhen City. Overall, it presents a distribution pattern of high in the east and low in the west, high ecological safety zone is located in eastern Shenzhen City, partial region of Dapeng New District, Yantian District and Luohu District. Low ecological zone is mainly in western broad areas of Shenzhen City （2） Landscape ecological security situation is relatively poor in Baoan District, Futian District, Guangming New District, Longgang District, Longhua New district, Nanshan district ,while it is rela- tively good in Dapeng New District, Luohu District, Pingshan New District and Yantian District （3） Overlay space differentiation dia- gram of ecological security and the basic ecological line , lower and low landscape ecological security areas within the ecological line mainly is located in Longgang District, Nanshan District, and Guangming New District.
