The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

Land use degree of Guangzhou City is highly positive global spatial autocorrelated. The spatial autocorrelation types of Guangzhou City land use degree is distributed in a centric circle. High-high aggregation is in the central part and low-low aggregation is in the peripheral area. Non-aggregation and Sparse low-high and high-low aggregation are in the intermediate area. Decrease of Moran's I since 1995 shows the weakening of the single-center structure of land use degree.
广州市土地利用程度呈高度的正全局空间自相关,各局部空间自相关类型呈同心圆分布,中间为高高集聚,外围为低低集聚,两者之间为非集聚和零散的高低、低高集聚,呈现出单中心结构。1995年以后, Moran's I 有所下降,说明这种单中心结构在弱化。

Thirdly, The mathematics model of forecasting low flow was established in Fengcong and Fenglin regions according to these factors influencing the amount of low flow in karst drainage (the area of drainage, lithology, the type of landforms and its special assembly and forest)The conception of low water resources carrying capacity was firstput forward according to the changing law of low water resources in space and the situation of exploitation and utilization in karst drainage (ie, under the condition of the virtuous ecological environment and the available technology, the explorable amount of water resources in certain areas is capacity and limitation which is able to coordinate the development of population, enviroment and economy during the period of low flow seasons) and preliminarily analyzed its connotation, characteristic and established the index system of low flow in karst drainage.

The assessment result shows: the infirm zone of the aquifer basically distributes in the limestone area of low Ordovician -top Cambrian, which the cranny is uncovered and overgrown, the area is also the direct recharge area of spring basin. In addition , in the rivers valley area of Jin xiuchuan and Bei sha river, because the leakage of the river is serious, the contamination can leak easily to the groundwater in the area of surface and near the river, so this area also is the infirm zone. Frail zone distributes in the uncovered area of mid-Cambrian which the canny upgrowth is commonly, parts of the zone distributes the relatively impervious layer such as shale. In the north-west area where is the down-rivers of two rivers, the alluvium is thick, the protection to the limestone is good.
评价结果显示,济南岩溶泉域含水层很脆弱区基本分布在济南泉域的岩溶裂隙非常发育的、裸露的下奥陶~上寒武的石灰岩地区,该地区也是泉域的直接补给区,另外在锦绣川、北沙河等河谷地带,由于河床渗漏严重,地表水及近河地带污染物容易渗入地下,也为很脆弱区;脆弱区一般分布在裸露的中寒武地层区,岩溶裂隙发育一般,部分地带分布有页岩等相对隔水层;西北部两河下游冲积层较厚,对下伏石灰岩保护功能较强,属于脆弱性相对很低区。

Results indicated that according to the different newly increased cultivated land rate, land consolidation projects on the district or county level could be divided into four categories: land consolidation, cland consolidation and exploitation, land development and consolidation, land development. While according to the investment per unit area on newly increased cultivated land, it could also be divided into four categories: high investment, reasonable investment, partial low investment and low investment. Correlating curve type among the investment per unit area in newly increased cultivated land, average annual growth rate of GDP and average annual growth rate of per capita GDP was a compound one. Correlations among newly increased cultivated land investment per unit area and annual growth rate of per capita GDP, annual growth rate of per capita GDP and other economic development indexes showed an "S" changing tendency curve.
