汇水区 meaning in Chinese
catchment area
collection area
runoff area
Examples
- The main aim of system harness of man - made debris flow is to make potential debris flow not broken out and present debris flow decreased
控制固体物质补给是关键，合理设计规划弃土石渣的排放场地是重点，搞好汇水区水土保持系统工程是基础，调整沟床比降，减少水流动能，使泥石流暴发减少到最低程度。 - Finally , this paper proves that the method of automatic compartmentalization of rainwater catchments basin is easily operable and highly improves the efficiency and quality of the compartmentalization of rainwater catchments by instance
实验证明，雨水流域汇水区的自动划分方法不仅操作性较强，而且大大提高了汇水区划分的效率和质量。 - In the light of principles of optimizing landscape structure , we modulate and design the landscape structure of the study area , and put forward the program . development construction is estated on the basis of protect construct
通过分析重点渗露带的人口承载力，得出双龙、邵而汇水区，可进行适当开发建设，但人口规模应控制在2 . 5万人以内。 - ( 3 ) by analysis the environmental bearing capacity of emphasis leakage catchment water area , the main factor of limiting the development of the study area is the exploitation of the underground water resource and the population , thus when further constructed , it should not broaden the population scale and should to save the water quantity . dajiangou and beikang are out of the bearing capacity . real estate construction must avoid the two fields
( 3 )分析研究区内重点渗漏区汇水范围区域的环境承载力，得出限制研究区发展的主导因素就是地下水资源开采量及人口规模，因此研究区进行建设时，不易再扩大人口规模，应尽量节约水资源用量，可引用外水，大涧沟、北康2个汇水区均超出环境承载力，在进行区域开发建设过程中，应尽可能的避开这2个汇水区。 - In view of the existing problem in the traditional method of the compartmentalization of urban rainwater catchments basin , by the technology of partition of drainage basin and professional gis terrain disposal software , the paper proposes a method of automatically compartmentalizing the urban rainwater catchments basin by six steps : construct the grid dem , define the stream direction of grid nod , extract the catchments network , compartmentalize the sub - catchments , build urban rainwater catchments basin with sub - catchments , encode the rainwater catchments basin
摘要针对传统汇水区划分方法中存在的问题，利用流域地形分割技术，通过专业的gis地形处理软件，建立了城市雨水流域汇水区的自动划分方法，其划分过程主要由构建格网dem 、格网点流向定义、汇流网络提取、子汇流区域划分、子汇流区域生成城市流域汇水区和流域汇水区编码6步组成。
