九寨沟的湖泊植被

九寨沟湖泊植被的特点是;湖泊植物区系属北温带植物区系的一部分;植物群落类型仅有挺水和沉水两大群落类型,群落生态系列极不完整;湖泊植被大体仍保持着自然性和原始性;植物群落生存的水深较大(种子植物可生长在水深6.0米处,轮藻群落可在水深11.0米的湖床上发育),本文对九寨沟13个湖泊植物群落的组成、结构进行了描述。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
