赤红壤水土流失区发展持续农业的存在问题及对策

Existing Problems and Countermeasures of Developing Sustainable Agriculture in Latored Soil Erosion Regions

本文以广东省赤红壤水土流失区为例，综合分析了赤红壤水土流失区发展持续农业的存在问题，在此基础上提出了该区发展持续农业的途径与对策．认为：水土流失区发展持续农业存在的突出问题主要是土壤退化；发展持续农业的根本途径在于走生态农业的道路，建立立体农业生态系统；侵蚀土壤上重建森林植被群落首先要建立先锋群落，然后建立稳定的南亚热带森林植被群落。

By taking the latored soil erosion regions of Guangdong as examples, thepaper synthetically analysed the problems existing in developing sustainable agriculturein latored soil erosion regions, and on this basis put forward some ways and countermeasures to develop sustainable agriculture. It is suggested that, in the erosion regions,the conspicuous problem existing in developing sustainable agriculture should be soil degradtion; the fundamental way to develop sustainable agriculture should be to take ecological agriculture road and to found stereoscopic agro-ecosystems; for rebuilding forestvegetation communities on eroded soils, it should be essential to set up front communities, and then set up stable south-subtropical forest vegetation communities.
