为了控制水土流失,修复生态退化,对于中国黄土高原进行科学区划。以植被-侵蚀动力学理论为依据,将黄土高原划分为4个类型区:长城沿线区、黄土丘陵沟壑东区、黄土丘陵沟壑西区和黄土高原沟壑区。利用植被-侵蚀状态图,探讨了这4区控制侵蚀和修复植被的前景。该文所提出的综合治理策略是:黄土高原生态环境恶劣,只有黄土高原沟壑区具有自我修复功能,可通过治理,形成能承受一定程度破坏的植被;其他3区,只有通过小流域高强度治理,才能有效地改善植被和减少侵蚀,并需要持续的防护和治理才能维持。
In order to control soil erosion and restore ecological degradation, the scientific division of the Loess Plateau in China is carried out. According to the theory of vegetation-erosion dynamics, the Loess Plateau is divided into four types of zones: the area along the Great Wall, the eastern gully region of the Loess Plateau, the western gully region of the Loess Plateau and the gully region of the Loess Plateau. Using the vegetation-erosion state diagram, the prospects for controlling erosion and restoration of vegetation in these four areas are discussed. The comprehensive control strategy proposed in this article is that the ecological environment in the Loess Plateau is poor, and only the gully area of the Loess Plateau has the function of self-remediation. Through the management, the vegetation that can sustain some degree of damage can be formed. In the other three areas, Can we effectively improve the vegetation and reduce erosion and need sustained protection and management to maintain it.
