【摘要】 在搜集了中国西部亚高山针叶林主要分布区的行政区划信息及各针叶树种的分布信息的基础上,利用流行桌面GIS软件ArcView V3.2的Avenue开发出中国西部亚高山针叶林资源查询系统,该系统既可以查询任意一个属或种的分布情况,又可以查询多个属、种(同属的和不同属)的交叉分布情况,并且查询结果可以立即反映到电子地图上,图例也能立即更新。并且在查询单一种的分布情况时,还可以查询其相关图像、文本、视频等信息,大大丰富了种的查询内容。同时,该系统也可查询任意一个或多个省级行政区或县级行政区的属种分布及其组合情况,从而使得行政区和亚高山针叶林属、种的双向查询变得非常简单。另外,本系统具有很强的可扩展性,可以轻松实现亚高山针叶树种、行政区及图像、文本、视频的扩充,并且扩充的内容可以立即使用,达到随时扩充、随时使用的目的。更多还原

【Abstract】 On the basis of the information about the administrative division system and the distribution of main subalpine coniferous species in west China, A Query System of west China Subalpine Coniferous Forest Resources was developed by means of the popular desktop GIS software-ArcView V3.2 in terms of Avenue language. In the system, one can query not only the distribution information of one genus or species, but also the intersecting distribution information of multiple genera or species (belonging either to the same genus or to different genera). The query results can be reflected on the electronic maps and the legend for the results can be updated immediately. When one species’ distribution was queried, the relative information on the species in terms of video, text and image could also be displayed at the same time, which enriches greatly the querying contents. The system allows one query the distribution status of all genera or species and their combination situation at any one or more provincial or county levels in terms of administration district, which makes it easy to query genus-species database bi-directionally between administration area and subalpine coniferous forest. Moreover, the system has a strong expandability. It’s easy to extend subalpine coniferous genus or species, administration division, image, text, video. The extended information can be used as scon as it is extended.更多还原
