Lingshan scenic spot of the terrain Buddha like a small lingshan upholstery back, left, right, qinglongshan QingFeng on wuhushan white north and embrace hill, beauty of taihu lake, a Yi locats water, this kind of traditional feng shui theoretically called "eight wind motionless, the" golden lotus sitting for land, the terrain is kept this auspicious reiki, so made big screens to collect the gas, but also through the content on the screens leads visitors into lingshan buddhist culture history in the world.

灵山大佛景区的整个地形尤如一张太师椅，背靠小灵山，左边青龙山，右边白虎山，北踏青峰，尽揽山形之美，南望太湖，一挹水色之秀，这种传统风水理论上称为"八风吹不动，端坐紫金莲"的地形是大吉之地，为保存这吉祥的灵气，所以造大照壁来收气，同时也通过照壁上的内容引领游客走进灵山的佛教文化历史世界。

Using successive regression and GIS technique, the regression equations of the precipitation and the topographical data in the upper-middle reaches of Yangtze River are established based on the 10 years daily、 mensal and annual precipitation of 613 meteorological stations, from 1992 to 2001. The topographical data include the elevation, aspect and slope form DEM of 4km resolution.

本文首先利用逐步回归和地理信息技术，最新的长江中上游613个气象站，1992～2001年10年降水资料，建立了日、月、年降水与4km分辨率的DEM高程、坡向、坡度等地形数据的回归方程，将降水量中地形影响部分分离出来。

A 4 Quantity Model (4QM) for partitioned area entities in terrain OTIN via combining topology relation with metric relation is proposed subsequently. Spatial topological relation and metric relation are described in one model.

将拓扑和度量关系相结合，本文给出了地形OTIN中剖分面状地理实体的4数模型(4QM)，使得拓扑关系和度量关系表达在同一个模型中。4QM可以作为地形OTIN中地理实体边界简化的参考。
