| 摘 要： | 利用基于GIS的黄土高原植被类型分布图,结合黄土高原地区标准气象站的气象因子资料,对黄土高原植被类型变化和空间分布对气象因子变化的响应关系进行了分析。结果显示:从东南到西北,年降水量、月平均最高气温、月平均最低气温逐渐减少,年平均气温、全年日照时数、全年最大蒸散量、平均风速逐渐增加,植被类型由东南湿润半湿润森林、半干旱森林草原往西北转变成轻干旱、重半干旱的温性草原、干旱的荒漠半荒漠植被。

| Abstract: | Digital maps of vegetation species distribution of Loess Plateau based on GIS were used combining the data of meteorological factors from standard meteorological stations of Loess Plateau to analyze the responses of vegetation variation and spatial distribution to meteorological factor variation.The results showed that from southeast to northwest,the annual precipitation and monthly average of maximum and minimum temperature dropped off.While the annual average temperature,annual sunshine duration,annual ma... |
