Abstract:: This study was carried out by using the combination of routine observation and gradient observation methods. Wind speed, soil temperature, light intensity, air humidity and other meteorological factors were observed for laminated protective forest and monolithic shelter belt of muddy coast protective forest in Liao River delta. The results showed as follows:laminated forest was sparse structure and its ventilated coefficient was 0.26, leeward areas in the forest 1H-5H (H was tree height) wind speed reduction within the range is the most significant with decrease by 38.51%～57.25%, 10H-20H within the scope of a relaxation, wind speed decreased about 8.19%～20.57%, the average wind speed within the forest was 62.86% lower than that outside of the forest. The single forest belt 1H-5H wind speed average range of fall was 41.54%～59.53%, 10H-20H average range of fall was 9.26%～16.14%. Soil temperature for inside of the forest was lower than that outside of the forest. Inside of the forest, daily average air humidity was higher than that outside of the forest which was up to 30.6%, for daily light intensity, inside of the forest was 34.7% lower than that outside of the forest. Summaries for this study were showed as follows:the effective windproof distance for laminated protective forest and monolithic shelter belt was 20H. Laminated protective forest had functions of improving microclimate of forest. It can increase air humidity for inside of the forest, reduce light intensity and control soil temperature.
