Based on the water resources survey of Shanghai in 1999 and the 1:50 000 color infrared aerial photos obtained in early 2000, a case study of the upper Huangpu River was carried out. The exponential method, pair-sample t test, and remote sensing analysis are used to analyze water environmental characteristics and land use pattern in the river network plain. In order to explore response of water quality in the waterhead region to the changes in land use and its driving force, five land use patterns are selected and a new type of exponential is designed.

以黄浦江上游水源地为例，利用1999年上海水资源普查数据及2000年初成像的上海市1：50000彩红外航空像片，采用GIS空间分析技术、灰色关联分析技术，划分土地利用样带，设计水质改善指数，探讨平原河网地区水环境质量对土地利用结构的响应，以及水源水质对土地利用变化驱动力的响应。

Cyanide in water, in tissues of aerial part of plants and in air was analyzed spectrophotometrically. Results from this study indicated less than 10.85% reduction of the applied iron cyanide complex was detected in hydroponic solution in the presence of plants. Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.

结果表明：(1)低浓度实验组52.99mg CN L^(-1水溶液中10.85%的亚铁氰化物被植物吸收，随着浓度的升高吸收到植物体内的亚铁氰化物的比例依次递减，但是统训学分析显示各实验组单位体重的植物吸收亚铁氰化物的量无显著性差异；(2)在植物的各个部位都能检测到微量的亚铁氰化物，表明亚铁氰化物通过植物的蒸腾作用在植物体内的迁移。
