摘要：

为探讨雷竹集约化栽培对周边河流水质的动态变化的影响，在雷竹栽培区与天然林区河流各设置3个水质监测断面，于2006年5月—2007年5月每2个月进行采样，对主要水化指标进行分析。结果表明：雷竹栽培区河流水质状况明显差于天然林区，水体中所有水化指标均表现为雷竹栽培区高于天然林区。总氮、硝氮、氨氮和有机氮含量丰水期高于枯水期，而总磷、可溶性碳、COD、BOD₅含量则表现为丰水期小于枯水期。雷竹栽培区水体中总氮含量年均达4.24 mg·L^-1，是天然林区水体的3.15倍，硝氮含量为 2.01 mg·L^-1，是天然林区的5.07倍，氨氮含量为0.07 mg·L^-1，比栽培区水体高0.66倍；水体中总磷含量雷竹栽培区平均达0.05 mg·L^-1，是天然林区的2.39倍；可溶性碳含量平均达17.78 mg·L^-1，比天然林区高出2.87倍。雷竹集约化栽培引起了周边水体氮、磷和可溶性碳的污染。

Abstract:

Water samples from two near rivers respectively around bamboo stands and natural forests were collected in three sampling points in two months interval from May 2006 to May 2007. It was found that the quality of water systems under the bamboo stands was much worse than that under the natural forest. The concentration of total N, nitrate N, and organic N in two rivers appeared higher in wet season (during March and May), than the other months that had less rainfall. However, the concentration of total P and dissolved C and the values of COD and BOD were much higher in dry season (during September and January), and the peak values of water from river around bamboo stands appeared in November. The average of concentrations of total N in water from river around bamboo stands was 4.24 mg·L^-1 and 2.15 times greater than that around the natural forest. The corresponding values for NO₃-N was 2.01 mg·L^-1 and 4.07 times, for NH⁺₄-N was 0.07 mg·L^-1 and 0.66 times, for total P was 0.05 mg·L^-1 and 1.39 times, for dissolved organic C was 17.78 mg·L^-1 and 2.87 times. The results showed that the river around bamboo stands was polluted by N, P and DOC.
