the area of Beijing and Tianjin sandstorm source control project;vegetation restoration;vegetation coverage

Regional vegetation restoration effect of the area of Beijing and Tianjin sandstorm source control project is the crucial part for environment research of this area.Based on the traditional ecology field survey method,the plant diversity variation under the Beijing and Tianjin sandstorm source control project was studied.The original plant coverage date has been compared with that one which has been measured after the implementing of the first phase of the project by Normalized Difference Vegetation Index(NDVI) method for dimidiate pixel model.The results showed that the low covered area have reduced gradually,and the high covered area have increased correspondingly in the sandstorm source controlled area;and there are good vegetation restoration potential and tendency in this region.The average vegetation coverage has been risen in this area based on five-year efforts of the Beijing and Tianjin sandstorm source control project.The research results provide basic data and reference for second phase of the project.
