塔里木河流域农业化肥投入的环境影响分析

一直以来化肥已成为提高农作物产量的重要的物质投入，然而，由于受施用技术、施用方法、施用时间的影响，化肥施用的很大一部分未被利用而流失到了周围的环境中，化肥施用量越高，流失到环境中的数量越大，对生态环境的污染也越高。本文在分析塔里木河流域化肥施用强度和施用密度的基础上，分析了化肥施用带来的土壤、水、大气等的环境污染，进而探讨了流域农业经济增长与化肥施用残留之间的环境库兹涅茨曲线，以期能引起重视，采取措施，减少化肥污染。

The Analysis of Environmental Impacts of Chemical Fertilizer in Tarim River Rasin

For a long time, fertilizer has become an important material in the promotion of crop yields. However, influenced by the technology, method and time of fertilization, a large part of chemical fertilizer untapped and lost into the surrounding environment, and the higher amounts the chemical fertilizer, the bigger the quantities of the loss to the environment, and also the higher the harm to the ecological environment. Based on the analysis of applied strength and density of chemical fertilizer in the Tarim River basin , this chapter analyses the soil, the water and the air pollution which resulted from the runoff of chemical fertilizer. So as to bring the attention and take measures to reduce the pollution of chemical fertilizer, this paper also researches the relationship between the negative environmental impacts induced by fertilizer inputs and the growth of agricultural production by introduced into the environmental Kuznets curve from the empirical term.
