Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.

But at present the forests that can be cut down are fewer, so that the forestry industries are very difficult, and the situation has been very hard for the economic activities for the people there and the sustainable development of the city. Under such background, this paper does research on the problem of the sustainable development in the forestry resource-based city, find the relationship between the cut of the forest and economic development, and the problems in the economic develop process and the reasons of the declining. Then I construct the dynamic model of the sustainable development in economic in Yichun, in order to find the reciprocities among the population, resource and economics to provide more scientific data to the deciders. From the model, we can get the sustainable mode in the forestry resource-based cities.
