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。
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.
