垦荒的若干小气候效应

SOME MICROCLIMAIC EFFECTS OF RECLAMATION

中文摘要:

      本文应用呼伦贝尔草原开垦地和未垦地连续两年的野外观测资料,分析了垦荒后春夏之交(5—6月)土壤热、水状况,贴地层大气动力、热力状况及地表热量平衡特征等发生的变化。指出,垦荒的小气候效应是多方面的和明显的,特别各种热力效应尤为显著。因而,垦荒这一人类活动对气象状况的影响是值得重视的。

英文摘要:

      In this paper, the field observation data of cultivated land and uncultivated land at Hulunbeier for two years in succession are used.The authors analysed the variations of soil hydro-thermal condition, atmospheric dynamic and thermo- dynamic condition near the ground, and surface heat balances during the periad between Spring and Summer May-June after reclamation. It is indicated that the microclimatic effects of reclamation are many sided and obvious, especially, the thermodynamic effects. So one must pay attention to the influences of reclamation such a human activity on climatic conditions.
