钢铁工业区不同园林绿地配置模式生态效益评价——以韶钢为例

Ecological Benefits Evaluation on Different Landscape Plant Configuration Patterns in the Iron and Steel Industrial Estate——Take Shaosteel as An Example

为探讨如何使钢铁企业里有限的绿地系统发挥最大的生态效益,对韶钢不同配置模式园林绿地的生态效益进行了评价。分别选取了韶钢3个不同污染程度厂区中5种典型园林绿地配置模式进行降温、增湿、减噪及消纳总悬浮颗粒物4个方面的生态效益调查。结果表明:园林绿地的生态效益与其植被的配置模式直接相关,整个厂区不同配置模式园林绿地的综合效益依次为:乔木+灌木+草地>乔木+灌木>单乔>乔木+草地>灌木+草地,乔木在生态效益中发挥着主导作用,复层绿地模式具有明显的优势,复层优于单层,乔木、灌木优于草地。针对上述结果,为进一步提高韶钢园林绿地生态效益提出了相应的建议。

In order to explore how to maximize the ecological benefits in limit landscape system, 5 typical landscape plant configuration patterns in 3 districts of different contaminated levels in Shaosteel were studied,and 4 indexes（lowering temperature, increasing humidity, reducing noise and dissolving TSP） were evaluated.The results demonstrated that the ecological benefits of landscape were directly related to its plant configuration pattern, the sequence of the comprehensive benefits of different plant configuration patterns was as follows： arbor＋ shrub＋ herb〉 arbor＋ shrub〉 arbor〉 arbor＋ herb〉 shrub＋ herb, the arbors played the leading role in producing ecological benefits. Ecological benefits of multiple layer configuration patterns were better than the single layer configuration pattern, the ecological benefits of arbor and shrub were superior to herb＇s. According to the results, corresponding suggestions of improving the ecological benefits of landscape were put forward.
