| 摘 要： | 利用不同季节小气候加密观测和小气候常规观测资料,通过分析西吉月亮山禁牧草场和鸦儿湾荒地近地层气温、地温、风速、相对湿度等要素的差异和日变化特征,探讨了不同下垫面下小气候变化的趋势。结果表明:封山禁牧后,下垫面随之变化,会产生所谓的“绿岛效应”,尤其在植被生长旺盛的夏季,气温明显下降,空气湿度增大。说明封山禁牧这一措施对脆弱生态的恢复改造有明显的效果。

| Abstract: | The use of the microclimatic observation in different season analyzed the difference and daily variation of meteorological elements,such as the temperature,ground temperature,wind speed and relative humidity of ground layer in the grasslands of Yueliangshan and wasteland of Yarwan in Xiji,researched the variation trend of microclimatic on different glound layer.The results showed that decreased temperature and increased humidity,particularly in summer of an exuberant growth of vegetation,after closed hillsides to prohibit herding.Which gained effection significant to improve ecological environment. |
