摘要

Artificial fencing methods used to combat land degradatbn have unknown influences on vegetation restoration in the North East of China, especially at Yanchi Ningxia Hui Autonomous region. To determine their efficiency, data have been collected from 2003 to 2013 in several study fields which have implemented different desertification combating methods including: artificial fencing (core, edge and external). Using biodiversity methods based on plant community structure characteristics indices (such as Shannon Wiener diversity index, Simpson dominance index and the evenness index) and the biomass, height and weight have been measured. The results showed that the main factors influencing vegetation growth are not only climatic factors, but also human activities (animal grazing and farming). In addition, the comparison with the natural grassland measurements showed that the average biomass, coverage rate, height and density values of the fencing area are 2343.58 kg/ha ,39.26 %, 16.47 × 10~2m and 106.95 × 10~4n/ha respectively larger than the natural grasslands which are 1722.24kg/ha, 33.58%,13.55 × 10~(-2)m and 99.01 × 10~4n/ha, showing artificial fencing to be more efficient in regard to the soil crust generated that prevented the soil degradation by water and air erosion. To be efficient, the number of fencing years must be similar to the natural biological cycle of the species of the study area (5 years in Yanchi) and frequent checkups are suggested to maintain the plant community dynamic viable and profitable for human well being in order to meet their needs (animals grazing etc.) in such a way that sustainable development may be effective.
