| 摘 要： | 从汀江流域畜禽养殖业现状分析入手,依据排泄系数法原理,估算流域各县市的作物所需畜禽粪尿肥的最大量、畜禽污染物产生量和农田畜禽粪便负荷量,并对畜禽养殖影响水环境进行分析.从调查中分析中可知,流域集约化养殖场大多分布于中上游的长汀河、旧县河和汀江干流段,地理分布过于集中,局部地区环境风险较大.结果表明,畜禽粪便环境承载量较大的河流依次为:长汀河、濯田河、旧县河、黄潭河、汀江干流、永定河、桃溪河,整个流域的畜禽污染已对环境产生风险,尤其是长汀河、旧县河流域尤为突出.

| Abstract: | For the purpose of environment protection,the maximum admissible load of livestock manure in the watershed of Tingjiang was calculated based on the principles of soil-plant nutrition and the theory of scientific fertilization.Secondly environmental risk of livestock in each community within the watershed was evaluated.The results indicate that the pollution caused by livestock threatens the quality of the watershed with different extents,especially in the Chanting river and the Jiuxian river. |
