Abstract:: The effects of environmental factors(greenhouse light intensity，relative humidity，temperature，soil temperature) in the greenhouse or outside were surveyed by the weather change process in spring，such as rain，dust blowing and sand storm.The results showed that every disaster weather in spring produced remarkable influence on environmental factors in the glasshouse or outside.The light intensity，air temperature and soil temperature significantly decreased by rainfall，dust blowing and sand storm in the greenhouse or outside.The relative humidity increased by rainfall in the greenhouse or outside.The relative humidity decreased by dust blowing outside of the greenhouse；the relative temperature increased by dust blowing in the greenhouse.The temperature in the greenhouse was greatly lowering，while the temperature outside of the greenhouse less decreased.The environment factors changes in the greenhouse or outside were inconsistent with different weather change process.The light intensity outside the greenhouse was higher than that inside the greenhouse；the relative humidity，temperature and soil temperature inside of the greenhouse were higher than that outside of the greenhouse.and there was an obvious correlation between them.In dust weather，a great many techniques，which including tightening squeeze film wire，clearing dust，supplementing manmade light were implemented to improving illumination conditions in greenhouse.
