A Method of Land Degradation Assessment in the Inter-distributing Area of Farming and Pasturing of Northwestern Liaoning Province |
| |
| Abstract: | We took Zhangwu County in the northwest area of Liaoning Province as a case to study the method of land degradation assessment in the inter-distributing area of farming and pasturing. The results showed that it was a simple and practical method,which was based on the ecosystem succession stage of land types to assessment land degradation.And the ecosystem succession stage of land types could provide more information, which made the process of land degradation assessment more simple and more precise. |
