摘要/Abstract

摘要： 为了构建华北平原潮土区生态安全格局,并为其区域生态修复及农业可持续发展提供实践路径,基于土地利用、归一化植被指数（NDVI）、高程及植被净初级生产力（NPP）数据,综合运用形态学空间格局分析（MSPA）与最小累积阻力（MCR）模型提取区域主要生态源地、综合生态阻力面与生态廊道,构建区域生态安全格局并提出优化方案。结果显示,共识别出一级生态源地10处和二级生态源地6处,总面积为3 528.4 km²,集中于项城市、夏邑县、鄢陵县等淮河流域上游河流湿地;共提取出31条生态廊道,总长度为2 543.3 km,且呈现出沿河分布且依赖农田林网的特点,但受人类活动干扰显著,大多分布在研究区南部的鹿邑县和郸城县。基于生态安全格局评价结果,提出了沿黄生态保育区、南部生态发展保护区及平原农业生态修复区的生态功能分区及安全格局优化方案。

Abstract: In order to construct the ecological security pattern of the fluvo-aquic soil area in the North China Plain and provide a practical path for its regional ecological restoration and sustainable agricultural development, based on the data of land use, normalized difference vegetation index (NDVI), elevation and net primary productivity (NPP) of vegetation, the morphological spatial pattern analysis (MSPA) model and minimum cumulative resistance (MCR) model were used to extract the main ecological sources, comprehensive ecological resistance surface and ecological corridors in the region, the regional ecological security pattern was constructed and the corresponding optimization schemes were proposed. The results showed that a total of 10 primary ecological sources and 6 secondary ecological sources were identified, with a total area of 3 528.4 km², which were concentrated in the upstream river wetlands of the Huaihe River Basin, such as Xiangcheng City, Xiayi County and Yanling County. A total of 31 ecological corridors were extracted, with a total length of 2 543.3 km. They were distributed along the river and depended on the farmland and forest network, but were significantly disturbed by human activities, mostly distributed in Luyi County and Dancheng County in the south of the study area. Based on the evaluation results of the ecological security pattern, the ecological function zoning and security pattern optimization schemes of the ecological conservation area along the Yellow River, the southern ecological development protection area and the plain agricultural ecological restoration area were proposed.

Key words: the plain region of fluvo-aquic soil, ecological security pattern, minimum cumulative resistance (MCR) model, morphological spatial pattern analysis (MSPA) model, ecological functional zoning, Henan Province
