我省是全国水土流失较严重的省份之一。全省山丘区面积7.9万km~2,约占总面积的一半,建国初期水土流失面积达6.06万km~2(仅为水蚀面积),占山丘区面积的70%以上。长期以来,严重的水土流失导致土地资源退化,地力下降,旱涝灾害加剧,生态环境恶化,使农业生产发展基础脆弱、后劲乏力,成为制约我省山区农业持续、快速、健康发展的主要因素。因此,搞好水土保持,保护和优化生态
The province is one of the provinces where the soil and water loss is more serious. The hilly area of the province covers an area of 79,000 km ~ 2, accounting for about half of the total area. During the early years of the PRC, soil erosion reached 60,600 km ~ 2 (water erosion area only), accounting for more than 70% of the total area of the hill area. For a long time, severe soil and water loss has led to the degradation of land resources, decline in soil fertility, increased drought and flood disasters, deterioration of ecological environment, weakening the foundation for agricultural production development and lack of stamina, which have become the main factors restricting the sustainable, rapid and healthy development of agriculture in mountainous areas in our province. Therefore, do a good job soil and water conservation, conservation and optimization of ecology
