城市园林绿地建设土壤污染问题及对策研究
摘 要
随着城市化进程的加速，园林绿地作为城市生态系统的重要组成部分，其土壤污染问题日益凸显。本研究旨在探讨城市园林绿地建设中的土壤污染现状及其成因，并提出相应的治理对策。通过对北京、上海、广州等典型城市的园林绿地进行实地采样与分析，结合文献调研和GIS空间分析技术，揭示了重金属、有机污染物及农药残留等多类污染物的分布特征及其潜在风险。研究发现，工业活动、交通排放及农业面源污染是导致园林绿地土壤污染的主要来源。基于此，本研究提出了“源头控制-过程管理-末端修复”三位一体的综合治理策略，强调通过优化土地利用规划、加强污染物排放监管以及推广生态修复技术等手段，实现园林绿地土壤质量的持续改善。

RESEARCH ON SOIL POLLUTION PROBLEM AND COUNTERMEASURES OF URBAN GARDEN GREEN SPACE CONSTRUCTION
ABSTRACT
With the acceleration of the urbanization process, as an important part of the urban ecosystem, the soil pollution problem of the garden and green land has become increasingly prominent. The purpose of this study is to investigate the status and causes of soil pollution in the construction of urban garden green space and propose corresponding countermeasures. Through field sampling and analysis of green gardens in Beijing, Shanghai, Guangzhou and other typical cities, combined with literature research and GIS spatial analysis technology, the distribution characteristics and potential risks of heavy me tals, organic pollutants and pesticide residues were revealed. It is found that industrial activities, traffic discharge and agricultural non-point source pollution are the main sources of soil pollution in garden green space. Based on this, this study puts forward the comprehensive management strategy of "source control-process management-end restoration", which emphasizes the continuous improvement of soil quality of garden green space by optimizing land use planning, strengthening the supervision of pollutant emission and promoting ecological restoration technology.
