省委提出在西山地区实行以林牧为主的建设方针,是一个长远的战略目标,是从农业现代化的要求出发,因地制宜,适当集中,实行生产区域化,专业化的一个重要部署。本文根据西山地区自然资源和经济特点的现状,对如何实现这个目标,谈一点粗浅的看法。要把水土保持放在首位西山地区最大的特点是水土流失严重。全区二十八个县,总面积四万六千二百平方公里,水土流失面积就有三万一千四百平方公里,占到百分之六十七点九。每年平均输入黄河的泥沙量多达两亿九千万吨。也就是说,在西山地区的整个土地上,每年有五毫米厚的表层肥土被冲刷流入黄河。水土流失造成的恶果是:山尖、垣残、川少、地小、沟壑纵横,支离破碎,风沙迷漫,生态平衡遭到破坏,生产条件极差,农业生产水平低
The provincial party committee put forward the principle of establishing a forest-animal husbandry-oriented construction policy in the Xishan area. This is a long-term strategic goal. It is an important deployment of regionalization and specialization in production due to the requirements of agricultural modernization and proper concentration in accordance with local conditions. Based on the current situation of natural resources and economic features in Xishan area, this article talks about how to achieve this goal. To soil and water conservation in the first place Xishan area is the biggest characteristic of serious soil erosion. Twenty-eight counties throughout the district, with a total area of 46,200 square kilometers, soil erosion area there are 31,400 square kilometers, accounting for 67.9%. The annual average amount of sediment input into the Yellow River reaches 290 million tons. In other words, five millimeters of topsoil is flushed into the Yellow River every year throughout the entire Xishan area. Soil erosion caused by the consequences are: mountain tip, residual wall, less Sichuan, small, gully aspect, fragmented, romantic, ecologically balanced destruction, poor production conditions, low level of agricultural production
