| 摘 要： | 利用气候—地貌—植被模式,在充分考虑人类活动因素的基础上,将江河源区划分为黄河东部河谷高原暖温半干旱农牧交错水土流失生态大区、高原凉温带大区、高原冷温带大区、高原寒带大区4个大区;再分别以降水、植被和人类活动为主要因子,将其划分为7个二级区,11个三级区。

| Abstract: | The source region of Yangtze River,Yellow River and Lantsang is very broad,the terrain and physiognomy are rather complicated,the weather shows difference in vertical direction,and the plant distribution is obviously different in different areas.On the mode of Weather-physiognomy-plant and the factitious factors,the region is divided into four larger districts such as Plateau warm temperate zone,plateaus of cool temperate zone,plateau cold temperate zones and plateau frigid zone.Then,according to the precipitation,vegetation and human activity,it has been further divided into seven sub regions,eleven third-class regions. |
