河南农业大学郑州市文化路校区生境划分与营造

Habitat division and construction of Zhengzhou Wenhua Road campus of Henan Agricultural University

以河南农业大学郑州市文化路校区为例,在校园内选取70个样点,采用植物冠层仪(CI-110)拍摄了107张鱼眼镜头照片获取SVF数据,分析校园内各场地空间围合程度,并在Rhino软件中建立校园模型,使用Ladybug参数化插件,模拟校园场地的日照时长,找出其对绿地生长所需生态因子的影响。最终从城市局地气候、城市空间组成、空间形态、空间围合程度和场地设计因素5个方面,将河南农业大学郑州市文化路校区划分成15种生境类型。其中,种类最多的生境类型为建筑旁绿地生境,共7种,面积最大的生境类型为室外运动场生境,占36.7%。根据场地条件提出30条生境营造策略,以此来改善校园绿地生态环境,提高生物多样性。

Take Zhengzhou Wenhua Road campus of Henan Agricultural University as an example,we chose 70 sampling points in the campus,use CI-110 to shoot 107 fish eye lens photos to get SVF data to analyze the enclosure degree of various site space in campus.We also we establish campus model in Rhino,use Ladybug to make plug-in parameterization and imitate the sunshine duration to find out its influences on the ecological factors need for green land.At last we taking 5 aspects,such as city reginal climate,city space component,space situation,space enclosure degree,and site design factor into consideration,we divide Zhengzhou Wenhua Road Campus of Henan Agricultural University into 15 ecological environment types.Among them,the habitat type with the most types is the building side green space habitat,a total of 7 types,the largest area of the habitat type is the outdoor playground habitat,accounting for 36.7%.According to the site conditions,30 habitat building strategies were proposed to improve the ecological environment of campus green space and enhance biodiversity.
