摘要
城市化的结果使人口在城市高度的集中 ,人类对地表的改造强度已远远超过自然营力 ,产生了形态各异的永久性建筑体 ,这种高差起伏的人工建筑体构成的地表形态形成了城市人工地貌。由于技术手段的影响 ,城市人工地貌研究国内鲜见报道 ,其地貌图的编制至今仍然是个空白 ,本文以大连市为例 ,运用普通地貌学原理 ,借助 Surfer7.0技术编制了我国第一幅城市人工地貌图。 Surfer7.0应用 ,实现了等值线图 ,剖面图的自动绘制 ,其中的矢量叠加技术可以综合不同平台下的地学信息 ,并且避免了传统手工绘图中出现的小区域地图信息模糊现象 ,提高了地图信息的表达性。
The result of urbanization makes people concentrate to the urban. Mankind produce permanent building body that forms the urban man-made landscape. Because of the limited technology, urban man-made landscape studies were rarely reported in domestic. The establishment of geomorphologic map is still a blank till today. This paper taking Dalian as an example, Using the ordinary geomorphology principle the first urban man-made landscape geomorphologic map of our country through Surfer7.0 technology was worked out.Comparing with traditional natural establishment of geomorphologic map the establishment of urban man-made landscape geomorphologic map of CAD has its own remarkable characteristic.1. The establishment of urban man-made landscape geomorphologic map regards the traditional geomorphologic map as its foundation. Draw lessons from the traditional geomorphologic map in a large amount on the method and the train of thought. Investigating in the field and designing indoor, none of them can be dispensed with each other.2. The application of computer can store man-made landscape magnanimity map datum effectively. Achieving utilization of map datum freely. In addition, the use computer can speed up ofmap making obviously , and it is more accurate to make maps.The application of Surfer7.0 changes the traditional cartography of equivalence map and section map. We can use it drawing map automatically according to the three-dimensional data of man-made landscape that are offered. Also we can say that it has promoted the development of cartography greatly. In the course of carrying on connecting the figure of Surfer, MapInfo and CorelDraw, etc., We not only succeed in and connect each other but also find vector superpose technology that can synthesize information from different platform. This technology achieves sharing of information. This will have great push, reference function for the future research. The utilizing prospect is very widely.3. Surfer7.0 and other relevant software also make map information express clearer in man-made landscape geomorphologic map, which Avoid fuzzy information phenomenon appearing in little regional map while drawing by hand.
