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。

The high-resolution simulation results show very detailed planetary boundary layer characteristics in relation to terrain effects under prevailing northeasterly wind.

此高解析度模拟结果显示，在东北季风下，北台湾边界层明显受环境风场及地形效应影响，在山势较高处，晚上边界层之高度较低，且其分布与地形高度变化颇为一致。

Build scene method to basically have: 1, dig a lake to pile mountain, model landform, decorate billabong of river river lake, monarch diameter builds a road, create landscape situation; 2, build building, stage, booth, cabinet, hall, house, a small room, a pavilion or house on a terrace, corridor, bridge, boat, a screen wall facing the gate of a house, wall the building facilities such as door of path of wall, stair, Deng, scene, create building situation; 3, fold big pool of rockery, strange peak, hole, Wei Ya with block build by laying bricks or stones, create rockery situation; 4, decorate valley, mountain stream, riprap, onflow, create mountain stream situation; 5, bluff of megalith of load one's writing with fancy phrases, come down in torrents of pilot a ship into a harbour and below, create chute situation; 6, set shallow water small pool by landform, build stone hill fountain, put in a suitable place to breed view and admire fish, lotus of cultivated carry on one's shoulder, Lu Di, flowers and plants, build Shui Shijing; 7, with different combination, decorate community to line and season photograph change or highlight the stance of isolated tree in order to reflect Lin Ji, or clip is arboreous, those who make have all sorts of pattern, create situation of flowers and trees.

造景方法主要有：1，挖湖堆山，塑造地形，布置江河湖沼，辟径筑路，造山水景；2，构筑楼。台。亭。阁。堂。馆。轩。榭。廊。桥。舫。照壁。墙垣。梯级。磴道。景门等建筑设施，造建筑景；3，用石块砌叠假山。奇峰。洞壑。危崖，造假山景；4，布置山谷。溪涧。乱石。湍流，造溪涧景；5，堆砌巨石断崖，引水倾泻而下，造瀑布景；6，按地形设浅水小池，筑石山喷泉，放养观赏鱼类，栽植荷莲。

Analysis and comparison of the model results show that the introducing of gravity wave drag to the model can improve the model performance to some extent and result in more realistic simulation, and the effect of envelope orography on regional climate simulation is less significant than that of gravity wave drag.

通过试验结果的对比分析发现，在模式中引入地形重力波拖曳作用可在一定程度上改善模式对气候系统和要素的模拟效果，使模拟结果更符合气候实况。包络地形对模拟结果也有一定的改善，但对于细网格的区域气候模式来说，其效果不如重力波拖曳明显。
