The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.

Crystal structural analysis reveals that, because water molecules bond to Cu atoms, the dhbd ligand can only adopt a hydroxyl oxygen atom to bridge two reversed U-shaped subunits into a novel centrosymmetric dual-U-shaped tetranuclear Cu structure. Each U-shaped frame consists of two crystallographically distinct Cu atoms, two dpphen ligands and one coordinated water molecule.

结果表明纯水凝胶浴中所成膜为指状多孔膜，随着凝胶浴乙醇体积分数的增加，膜指状大孔逐渐消失，在φ=40%的乙醇/水凝胶浴中转变为海绵状多孔膜；指状多孔膜和海绵状多孔膜熔点相对于原料分别提高了3.9℃和3.5℃，而结晶度相对于原料分别提高了16.1%和13.5%。

The Ni-Fe and Mg-Al-Fe-LDH show paramagnetism at normal temperature, the calcined samples of LDHs show super-paramagnetism. The magnetization increases with the higher Fe~(3+) content and is independent of the crystal structure of LDHs. Magnetization of the calcinates of Ni-Fe-LDHs is higher than the Mg-Al-Fe-LDHs.3. Two novel SFME systems were found for the first time, that is furaldehyde/DMF/water and furaldehyde/ethanol/water system.

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。
