摘要:

为了探究人类活动对生态保护红线内生境造成的影响,提高生态保护红线监管能力,为完善生态保护红线监管制度提供科学支撑,以吉林省镇赉县为例,基于InVEST模型和GIS的空间分析能力,利用高分遥感影像及相关人类活动数据,从栅格尺度上评估生态保护红线区存在的生境风险。结果表明:研究区总生境风险值的范围介于0.00~1.32之间,高、中、低生境风险区域分别占红线总面积的2.31%、3.26%、22.12%,整个评估区内人类活动干扰对生境产生的影响以低生境风险为主;在各类生境中,林地的平均生境风险值最高,其中乔木林地、灌木林地、其他林地的平均生境风险值分别为0.58、0.88、0.79,同时最高风险值(灌木林地)也出现在林地生境中;相较于其他人类活动,城镇村及工矿用地的累计风险值和平均生境风险值均最高,分别为2 933 161.90、1.24,公路用地次之,分别为1 086 264.68、1.19,旱地、水田、渔业等人类活动对生境产生的影响有限。

Abstract:

In order to explore the impact of human activities on the habitats within the ecological conservation redline, improve the supervision ability of the ecological conservation redline and provide scientific support for improving the supervisory system of the ecological edprotection red line. Taking Zhenlai County of Jilin Province as an example, the high-resolution remote sensing images and related human activity data were used to assess the habitat risk of the area of ecological conservation redline form grid scale based on InVEST model and the spatial analysis capability of GIS. The results showed that: The total habitat risk value in the study area ranges from 0.00 to 1.32. High, medium and low habitat risk areas respectively accounted for 2.31%, 3.26% and 22.12% of the ecological conservation redline area. The impact of human activities disturbance on the habitat in the entire assessment area was dominated by low habitat risk. Among various habitats, the average habitat risk value of forest land was the highest, among which the average habitat risk values of arbor forest land, shrub forest land and other forest land were 0.58, 0.88 and 0.79 respectively, and the highest habitat risk value (shrub forest land) also appeared in the forest land habitat. Compared with other human activities, the cumulative habitat risk values and average habitat risk values of urban village and industrial and mining land were the highest, which were 2 933 161.90 and 1.24 respectively, followed by highway land, which were 1 086 264.68 and 1.19 respectively. Human activities such as dryland, paddy field and fishery had limited impacts on the habitat.
