广东南江工业园对其生态环境的影响分析

Analysis of the ecological environmental impact on Nanjiang Industrial Estate building in Guangdong Province

南江工业园地处北江江边,内设有电镀、五金加工企业,为查明工业园所在区域的环境状况,确定本项目对周边生态环境的影响,对南江工业园的陆地生态环境和水生生态环境进行了调查,结果表明工业园对其陆地生态环境造成一定的影响,约333hm2土地受到占用及将受到破坏,其中挖方、填方造成的水土流失量分别为110t·km-2·a-1、225t·km-2·a-1,而采取水土保护措施后,挖方、填方造成的水土流失量分别为58t·km-2·a-1、45t·km-2·a-1。在水生态方面亦对水生生物造成了一定的直接影响。

Nanjiang Industrial Estate is located near the north branch of Zhujiang River, there are some metals machining, plating factories. To investigate the present condition of the ecological environment around Nanjiang Industrial Estate, we investigated the land ecological environment and the aqutic environment around Nanjiang Industrial Estate. The result showed that the Industrial Estate building had certain influence on the land ecological environment. To some extent about 333 hm2 lands will be occupied and spoilt, in which the water and soil loss of excavation and fill were 110 t·km-2·a-1 , 225 t·km-2·a-1, but after adopting the protective measures, the water and soil loss of excavation and fill were 58 t·km-2·a-1, 45 t·km-2·a-1 respectively. The Industrial Estate building also had some impacted on the hydrobiont of the water body.
