Study On The Ecological Effect Of Agricultural University Green Space In Huhhot, Inner Mongolia Of China

Campus green space in accordance with the heterogeneity of micro-climate, vegetation types and ecological characteristics, through the dense forest that is before the right of main building, pine forest that is before the north gate, open forest and grassland in East of South Gate, in Eastern of Agricultural University in Inner Mongolia, investigate micro-climate factors. In accordance with canopy densities,more than 0.7 is the dense forest,0.3-0 .7 is open forest and grassland, less than 0.3 is scattered grassland zone ,which is divided into three kinds of green type. Eastern playground is CK.In august 2008 to august 2009 period, micro-climate related factors was measured by Kestrel 3000, and was statistical analysis.The results showed that:①Obviously green has warm winter and cool summer, dry winter and wet summer, wind speed is big in winter and wind speed is small in summer.②Planting arbor tree, shrub and grass dense mixed forest`s wind speed is small, temperature is high, humidity is low in winter; humidity is high in summer.Arbor tree dense forest`s wind speed is big, temperature is low, humidity is center in winter; humidity is low in summer. Open forest and grassland`s wind speed is center, temperature is center too,humidity is high in winter; humidity is center in summer.③Results indicated that around green space there existed a spatial gradient effect field.The field intensity decreased from the center of green space to the margin.④In summer,planting arbor tree, shrub and grass dense mixed forest`s wind speed is big,temperature is low, humidity is high,open forest and grassland and arbor tree dense forest`s wind speed is samll, temperature is low, humidity is high at 1m. In winter, Planting arbor tree, shrub and grass dense mixed forest`s wind speed is big, temperature is low, humidity is low; open forest and grassland and arbor tree dense forest`s wind speed is big, temperature is low, humidity is low at 1m.⑤According to the research on the temperature and humidity index THI contrast, open forest and grassland `s comfort level > arbor tree dense forest`s comfort level > planting arbor tree, shrub and grass dense mixed forest`s comfort level > playground`s comfort level .In the Forest`s comfort level> edge of forest`s comfort level> outside the forest`s comfort level> playground`s comfort level.
