The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.
摘 要:2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查,结果表明,投礁后礁区海域游泳生物的资源密度明显比投礁前高,增加了25.63倍;礁区海域各类资源种类均比投礁前丰富,总种数由投礁前的23种增加至41种,比投礁前增加了0.78倍,其中,蟹类种数增加最多,增加了1.75倍;在本底调查中没有出现的经济种类龙头鱼 Harpodon nehereus 和红星梭子蟹 Portunus sanguinolentus 在跟踪调查中已成为主要优势种;Shannon-Wienver多样性指数在礁区和对比区均比投礁前有所增加。

Composition of both spermatophyte and pteridophyte flora of a relict Alsophila spinulosa community in Wutongqiao Nature Reserve of Leshan region was discussed. It shows the proportion of Tropic and Cathaysia elements in both spermatophyte flora and pteridophyte flora was almost 2/3 of the total at the genus level, and even more at the family level. There was a distinct ancient endemism phenomenon in spermatophyte flora, owning to being 8 relict and remnant endemism genera in the total of 9. Furthermore, the proportion of Tropic and Cathaysia elements both at family and genus level in the pteridophyte flora were much greater.

During 1980 to 2002, the whole patch's quantity increases and has the phenomenon of crumble. In addition, the distribution of each patch becomes more disperse gradually, and the enchase decreases. During 2002 to 2006, after the creek engineering project has been put in place for several years, the whole landscape structure starts to become in ordered. Proven by the bird research data, higher sample are mostly scatter along the river side. Therefore, the creek engineer is able to stabilize our environment, and the big patch is increasing because of the plan of patch, as a result, the variety of birds in the testing area increases by a significant number.
於1980 ~ 2002年间,在人为大力开发加上天然风灾肆虐下,整体块区之数量渐增且形状有呈现破碎化之现象,而各类别块区之分布逐渐分散,且镶嵌度亦有下降之情形。2002 ~ 2006年,经逐年之野溪工程整治,整体景观结构有朝向规整化的情形,且以鸟类调查资料验证,丰度较高之样点大多沿著溪流分布,故可得知,野溪工程之施作对环境有稳定之功能,且因块区之规整使大块区数量增加,亦使研究试区之鸟类生态丰富度增加。

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。
