| 摘 要： | 分析了城市生态地球化学评价的特点。建立了城市生态地球化学评价的盖子模型。按照盖子的阻隔效应,将城市生态地球化学评价分为盖上循环、盖下库内循环和盖子网眼及边缘的库内外开放性循环三大部分内容。城市化进程就是盖子的扩张与修补过程。按盖子模型进行的城市生态地球化学评价有利于预测和防治城市生态地球化学灾害,为城市规划、建设和管理服务。

| Abstract: | A new "cover" model for evaluating urban eco-geochemistry has been proposed based on the characteristics of urban eco-geochemistry evaluation.According to the blocking effect of the "cover",urban eco-geochemistry evaluation concerns three parts:circulation of chemical elements or compounds on the cover,circulation of chemical elements or compounds below the cover (or in the soil reservoir),and open circulation of chemical elements or compounds between the cover surface and the soil reservoir through the cracks (called as net holes) or along edges of the cover.The urban development may be described as the expansion and reconstruction of the cover.The evaluation of urban eco-geochemistry based on the new "cover" model may help predict and prevent urban eco-geochemical disasters effectively and serve urban planning,construction and management. |
