摘要

[目的

]

对城市综合生态安全格局进行构建，为城市总体规划和城市生态规划等专题研究提供科学参考。[方法

]

以福建省南平市延平区为研究对象，在划定生态保护红线的基础上选择生态源地，以地形坡度、土地覆盖和植被覆盖为阻力因子，应用最小累积阻力模型，以生态阻力面直方图分布的突变点2 983和9 268为界，分别构筑延平区底线型、缓冲型和理想型生态安全格局。[结果

]

延平区生态源地，即底线型生态格局用地面积为534.51 km

，占延平区面积的20.10%；缓冲型和理想型生态安全格局用地面积分别为771.17和1 592.79 km

，占到延平区的29.00%和59.89%。结合这3种不同安全水平的生态安全格局，进一步明确了生态源地间的13条生态廊道和5个关键生态节点，共同组合形成了延平区综合生态安全格局。[结论

]

在生态保护红线的基础上，结合延平区山水型城市的特点，确定了不同安全水平的生态用地分布格局、生态廊道和关键生态节点，形成了延平区综合生态安全格局。

Abstract

[Objective] The construction of a urban integrated ecological security pattern was studied in order to provide scientific references for special studies such as urban master planning and urban ecological planning.[Methods] Taking Yanping District of Nanping City

Fujian Province as the research object

the ecological source land was selected on the basis of the ecological protection red line. The terrain gradient

land cover and vegetation cover were used as the resistance factors

and the minimum cumulative resistance model was applied to the mutation point of the ecological resistance surface histogram distribution. 2 983 and 9 268 are the boundaries

and the bottom line type

buffer type and ideal ecological security pattern of Yanping District are constructed respectively.[Results] The ecological source area of Yanping District

namely the bottom line ecological pattern

covered an area of 534.51 km2

accounting for 20.10% of the Yanping District. The buffered and ideal ecological security pattern covered an area of 771.17 km2 and 1 592.79 km2 respectively

and accounting for 29.00% and 59.89% of Yanping District. Combining three different levels of safety and ecological security

the 13 ecological corridors and 5 key ecological nodes between the ecological sources were further clarified

and the comprehensive ecological security pattern of Yanping District was formed.[Conclusion] On the basis of the ecological protection red line

combined with the characteristics of Yanping District which is a landscape-type city

the ecological land distribution patterns of different safety levels

ecological corridors and key ecological nodes are determined

and the comprehensive ecological security pattern of Yanping District is formed.
