中文摘要: |
茶园建设一般以地形图作为辅助支持。Google Earth 能提供1∶10000~1∶50000 的小比例尺地形数据,通过构建数字高程模型,可为坡地茶园规划提供一种快速而较为精准的地形数据。以广东韶关一个茶园规划为例,通过在Google Earth 采集高程数据,利用克里格法选择高斯模型进行空间插值和构建数字高程模型,制作两种等高距地形图,并在茶园种植区划分与道路、灌溉设施、排水设施的规划中应用,为茶园的概念
规划与总体规划提供了一种地形图快速获取与应用的方式。 |

In general,the tea garden construction must be supported by topographic map. Google Earth can provide 1∶10000-1∶50000 small scale terrain data,which can provide a fast and precise terrain data,by the construction of Digital Elevation Model. This paper collected elevation data in Google Earth,constructed the digital elevation model with a Gaussian model of Kriging method by spatially interpolating,and made the topographic maps with two types of contour interval to apply in planting region division,planning of roads,irrigation equipments,drainage facilities,taking a tea garden planning of Shaoguan City in Guangdong province as an example. It provides a way to make topographic maps quickly and support tea garden concept planning and the overall planning. |
