The 26 sample sites in 7 study plots adjacent to asphalt road and earth road in coastal wetland in the Yellow River Delta were selected to quantify plant diversity using quadrat sampling method in plant bloom phase of July and August 2012. The indice ofβTand Jaccard’s coefficient were applied to evaluate the species diversity. The results showed that the plant diversities and alien plants were high in the range of 0–20 m to the road verge. There were more exotics and halophytes in plots of asphalt roadside than that of earth roadside. However, proportion of halophytes in habitats of asphalt roadsides was lower than that of earth roadside. By comparingβ-diversity, there were more common species in the asphalt roadsides than that in the earth roadsides. The similarity of plant communities in studied plots of asphalt roadsides and earth roadsides increased with increasing the distance to road verge. The effect range of roads for plant diversity in study region was about 20 m to road verge. Our results indicate that the construction and maintenance of roads in wetland could increase the plant species diversities of communities and risk of alien species invasion.

Though Chiang Kai-shek may vow to “sleep on faggots and drink gall” until the mainland is liberated, he has some reason to rest more easily today than at any time in his long career as Nationalist leader. On the mainland his government never clearly controlled more than one of China's three “key economic areas” (the Yellow River plain, the Yangtze valley, and the Szechuan basin). At least he can effectively control Formosa, a realm 1/260th the size of the mainland. Nationalist cells permeate schools, factories and government bureaux. Local police organisations, semi-autonomous in mainland days, are now under the central control of loyal mainlanders. The powerful security force, the Formosa Garrison Command (FGC), operates under martial law. The two minority parties are as impotent as their mainland counterparts. There are no treaty ports to harbour leftist critics and the mountainous half of the island is effectively patrolled by government forces painfully aware of the dangers of banditry and rebellion.
