公园水景面积设计探讨

The Study on Water Allocation and Area Quantification of Park Waterscape

从节约水资源角度出发,对综合性公园水景面积进行定量研究。运用手持GPS仪对北京市12个典型公园的水景面积、建筑基底面积、道路铺装面积、绿地面积进行调查,探索水景面积与其他景观要素之间的关系,结果发现,公园水景面积比例与绿地率之间有显著的线性回归关系。结合《公园设计规范》建立公园水景面积比例与绿地率之间的方程组,运用单纯形法,求解发现,在绿地率不小于30%,建筑密度和道路铺装面积比例之和在5%～23%的约束条件下,水景面积比例范围是0～52.3%。该结果为公园水景定量化设计提供初步参考依据。

The area quantification of all-around park waterscape was studied from water resource saving point.To explore the relationship between the waterscape area and other landscape factors in park,the area of waterscape,building base,road and pavement and green space were investigated with a handheld GPS,and the results showed it had significantly linear regression relations between the percentage of waterscape area and the percentage of green space,and the model was established.According to＂The Park Design Code＂,the equations between the percentage of waterscape area and the percentage of green space was set up,and as calculated it showed that the range percent of water area is from 0 to 52.3%if the sum percentage of architecture density and road paved area is in the range from 5%to 23%.The paper provide scientific basis for park waterscape quantification design.
