程海湖生态修复人工植物群落养护投入影响因子调查分析

Factors Affecting Maintenance Investment of Artificial Plant Community in Chenghai Lake Ecological Restoration

对程海湖生态修复人工植物群落浇水、施肥、修剪、除草、病虫害防治等养护管理投入进行调查统计,分析其绿地养护投入影响因子。结果表明:群落植物特征相同,立地条件不同,土壤砂砾石含量高、含水量低群落单位面积年均养护费高于土壤砂砾石含量低、含水量高群落;群落植物特征不同,立地条件相同,植物耐旱性强群落单位面积年均养护费低于植物耐旱性弱群落;群落植物习性相近,立地条件相同的湿生群落,单位面积年均养护投入差异不大。为此提出科学设计、严格管控施工质量,科学养护,加强绿地养护人员的技术培训等建议。

This paper investigated the maintenance and management investment of artificial plant community for ecological restoration of Chenghai Lake,such as watering,fertilization,pruning,weeding,pest control and so on,and analyzed the influencing factors of green space maintenance investment.The results showed that with the same plant community characteristics and different site conditions,the annual maintenance cost per unit area of communities with high soil sand gravel content and low water content was higher than that of communities with low soil sand gravel content and high water content;the annual maintenance cost per unit area of communities with strong drought tolerance was lower than that of communities with weak drought tolerance under the same site conditions;there was little difference in annual maintenance investment per unit area in hygrophytic communities with similar plant habits and the same site conditions.Therefore,this paper put forward some suggestions,such as scientific design,strict control of construction quality,scientific maintenance,and technical training to maintenance personnel.
