the basic ecological characteristics of eroded soil in quaternary red clay region arestudied briefly.
概括地论述在水土流失区侵蚀土壤基本生态特征;
in the whole explored area, medium eroded and medium-low eroded soil covers 71.69%, and the high eroded area is larger than the medium-high eroded one.
整个研究区中可蚀性土壤和中低可蚀性土壤占71.69%,高可蚀性土壤面积大于中高可蚀性土壤。
making the problem worse, most eroded soil carries pesticides and fertilizers and ends up polluting lakes and rivers. the polluted waters kill fish.
更为糟糕的是,大部分被侵蚀的土壤都含有农药和化肥,最终导致河流与湖泊的污染,受污染的水又导致鱼类死亡。
