摘要
以“十三五”国家重大水专项上海市青浦区金泽水源地雨水径流污染防控技术示范区——大莲湖为研究区域,针对示范区内岸带的类型及坡度、岸带土壤的性质和土著植物的种类进行系统的调研分析,为后续河岸带地表径流污染阻控技术研发提供基础数据资料支撑.分析结果表明:示范区周边主要护岸类型为近自然和硬质护岸,以缓坡为主;水生植物和陆生植物分别以荷花、芦苇和草本植物居多.此外,研究区采样点中,临近农田土壤全氮含量平均值在0.95 g/kg上下波动,高于进水闸附近土壤的0.42 g/kg;临近居民生活区、鱼塘养殖和农田区的土壤全磷含量多在1.58 g/kg以上,高于湖岸护坡土壤的1.10 g/kg;有机质平均含量为11.30 g/kg,其中植物密布区有机质含量较高,表明当地的鱼塘养殖业以及农业对土壤环境造成了一定污染.
In this paper,we consider the rainwater runoff prevention and control technology demonstration area of the Jinze water source area in Qingpu District,Shanghai-Dalian Lake;the research area is a national major water project from the“13th Five-Year Plan”.Our study includes systematic research analysis on the type and slope of the riparian zone,the nature of the riparian soil,and the species of indigenous plants in the demonstration area;the study provides essential data to support subsequent research on the use of experimental rainwater gradient control technology in the riparian zone. The analysis shows that the riparian zone in the demonstration area is comprised of near-natural and rigid riparian, with gentle slopes. The aquatic and terrestrial plants in the zone with the largest population include lotus, reed, and herbaceous plants, respectively. Among the sampling sites in the study area, the average total nitrogen content of the soil in the adjacent farmland fluctuated around 0.95 g/kg, while the soil near the inlet gate was measured at 0.42 g/kg. The total phosphorus content of the soil in the adjacent residential living area, fish pond culture, and farmland area was more than 1.58 g/kg, while the soil at the lakeshore berm was measured at 1.10 g/kg. The average organic matter content was 11.30 g/kg, with higher values recorded in the densely planted area. These results confirm that local fishpond farming and agriculture have contributed to pollution of the soil environment.
