| 摘 要： | 采用定点定时观测方法,在春夏秋3季对安塞县具有代表性的退耕模式如混交林、人工乔木林、人工灌木林及对照裸地进行小气候观测,选取光照强度、大气温湿度、土壤温度进行小气候特征分析。结果表明,不同退耕模式对小气候均有改善作用,较对照裸地降低了光照强度、大气温度和土壤温度,增加了大气湿度;混交林在改善小气候方面的作用最明显,人工乔木林次之,人工灌木林较差;季节更替对不同退耕模式的影响不明显。建议加大退耕还林力度,优化退耕地植被结构,增加退耕还林地区的植被覆盖率。 |

| Abstract: | Based on method of fixed-point and-time,the microclimate of several representative models of mixed forest,artificial arbores,artificial shrubbery and bare land of Ansai County were observed in the spring,summer and autumn,the microclimate characteristics included the light intensity,air temperature,relative humidity,and soil temperature.The results showed that different modes play a improving role,reduce light intensity,air temperature and soil temperature,increase air humidity;Mixed forest plays a signific... |
