农业生态环境敏感性地域分布及整治对策

Spatial Heterogeneity of Agricultural eco-environment Sensitivity and Counter Measure.

农业生态环境日益恶化,越来越引起社会各界的关注。有效的综合整治农业生态环境,已经成为科学界面临的一个挑战。中国农业主要面临的生态环境问题是水土流失、盐渍化和酸雨,三种农业生态环境在空间上存在着相关性。对于三种生态环境问题,提出的控制对策如下:盐渍化的治理对策为合理用水、施肥,种植合适的耐盐作物;酸沉降治理对策为种植抗酸作物和采用化学调控方法降低降对作物的损害;水土流失使用生态恢复工程和生态重建工程进行治理。

The agricuhural ecological environment degradation has been attracted more and more attention in China. It is becoming a challenge for scientists to find effective measures to tackle the agricultural ecological environmental problems. In this paper, we reviewed the spatial pattern and correlationship of major the agricultural ecological environmental problems： soil erosion, saltinization, and acid rain. The counter measures of solving these problems were suggested as follows： firstly, using water resources and fertilizer reasonably and choosing salt tolerance crops to control saltinization; secondly, choosing acid tolerance feed and using the chemical method to control acid rain; finally, soil erosion could be controlled by bioremediation.
