张北地区自然资源及生态状况综合评价与分析
Comprehensive assessment and analysis of natural resources and ecological conditions in the Zhangbei area
摘要
Abstract
This study aims to explore the background conditions of the natural resource elements and the dynamic distribution of ecological conditions in typical agricultural and pastoral intertwined zones.Focusing on the Zhangbei area,this study selected 15 assessment factors by comprehensively considering four types of resources:land,vegetation,groundwater,and minerals.Accordingly,this study conducted a comprehensive assessment of natural resource elements in the study area using the analytic hierarchy process(AHP).Meanwhile,the 2019-2022 average remote sensing ecological index(RSEI)values were calculated using the Google Earth Engine platform.Based on these results,the study area is divided into six ecological functional zones.The results indicate that from 2019 to 2022,the natural resource dominance and RSEI values of the study area showed a gradual decreasing trend from the low mountainous area encircling the southern part to the hilly area in the northwestern part.The study area exhibited moderate natural resource dominance,with RSEI values all exceeding 0.52.This suggests relatively favorable ecological conditions.In addition,the assessment results of natural resource dominance are closely related to RSEI,showing a positive correlation spatially.This verifies the importance of the background conditions of natural resource elements on ecological status.The ecological function zoning proposed in this study can serve as a scientific reference for the planning and development of Zhangbei areas.关键词
