一、按森林植被类型演替的规律,议订水土保持工作的战略目标广东的天然林,由南向北,按地理条件有热带雨林、热带季雨林、南亚热带季雨林、南亚热带常绿林、亚热带常绿林等不同的类型,不同森林植被类型对生境条件要求不同。某一森林植被类型遭受破坏时,生态环境起了变化,又会出现另一种森林植被类型。例如,亚热带的常绿林遭受破坏后,如立地条件较差,容易被强阳性的马尾松林入
First, according to the law of succession of forest vegetation types, discuss the strategic goal of soil and water conservation The natural forest of Guangdong from south to north, according to geographical conditions are tropical rain forest, tropical monsoon forest, south subtropical monsoon forest, , Subtropical evergreen forests and other different types of different types of forest vegetation on the habitat conditions require different. When a certain type of forest vegetation is damaged, the ecological environment has changed, and another type of forest vegetation will emerge. For example, after the subtropical evergreen forest is damaged, if the site conditions are poor, it is easy to be affected by strong positive Pinus massoniana forest
