西藏“一江两河”地区耕种土壤资源合理利用与改良初探

Rational Utilization and Improvement of Cultivated Soil Resources on “One River,Two Streams”Regions in Tibet

西藏“一江两河”地区耕地面积占全自治区耕地面积的５４．６％，该区太阳辐射强、光温水配合好、土壤的生产潜力大，但也存在着土壤肥力亟待培育和提高的问题。在总结西藏当地经验的基础上。

The cultivated areas on “One River,Two Streams” regions account for 54.6% of total cultivated areas in Tibet.In the regions,solar radiation intensity,light and temperature and water are better harmony with each other;and soils hold great potentials for agro production,but there still exist some unfavourable factors such as soil fertility needing to be further bettered and improved.Based on the summing up of the local experience and through part of observation and determination,the rational utilization methods and improvement measures of cultivated soil resources in the regions are suggested in this paper.
