Abstract: To evaluate wind disaster risk of new type solar greenhouse in Tianjin, based on the wind disaster investigation in field in recent 10 years, the wind disaster risk evaluation model of sola greenhouse was constructed according to nature disaster risk evaluation theory. Then, the authors calculated the risk index of different levels of wind disaster according to the evaluation model and analyzed its variation from meteorological stations, spatial scale and time scale, respectively. The risk index of the meteorological stations and space distribution result showed that: the risk index of mild and moderate wind disaster was higher in Ninghe, Hangu, Tanggu, Wuqing and Xiqing; the risk index of mild wind disaster (risk index between 0.62 and 3.15) was obviously higher than that of the moderate (risk index between 0.0 and 0.61) and severe disaster, and the risk index of severe disaster was nearly 0, because there was little wind disaster maximun with wind speed exceeding 17.2 m/s. In recent 10 years, the risk index of moderate and severe wind disaster basically hold the line. The risk index variation of mild wind disaster changes from 2.70 to 2.0 from 2005 to 2007 and fluctuates with 2.0 after 2007.
