随着国民經济建設的飞躍發展,我国的林地面积将迅速地不断增長,同时为了满足經济建設的需要,国家也将砍伐一部分林木。森林面积的增加和新陈代谢,将直接影响到气象及水文现象,包括对河川徑流、泥沙的影响和对于林区及其附近的小气候影响。有关建設部门迫切要求了解这些因素的变化,要求提供有关林区的科学数据,要求了解植树造林及森林对防止土壤侵蝕的作用、对洪峯削减的作用、对河川年徑流的影响及具体数据,为修改工程规划設計和提高生产的依据。
With the rapid development of the national economy, the area of forestland in our country will rapidly increase. At the same time, in order to meet the needs of economic construction, the country will also cut down some trees. Increased forest area and metabolism will have a direct impact on meteorological and hydrological phenomena, including impacts on river runoff, sediment and microclimate in and around forest areas. The authorities concerned urgently asked for changes in these factors, asked for scientific data on forests, asked about the role of afforestation and forests in soil erosion prevention, the role of flood reduction and river runoff, and specific data, To modify the project planning and design and improve production basis.
