The governments in the world and the whole society have been paying more and more attention on it. Eco-tourism is one of the best, the most important and sustainable approach to wetland utilization, but there was no any systematic researches at home and abroad. Therefore, the activity of eco-tourism is short of scientifical guide in theory and practice. South Dongting Lake is regarded as an internationally important wetland. By means of ecology, mathematics, eco-tourisrn, we expounded the fundamental theory and practice of wetland eco-tourism. The main research achievements were as following:(1)wetland landscape resources. We conducted a whole investigation of the wetland landscape resources from 2000 to 2002. It included the natural resources such as the soil, plants, waterfowl and animals, water resources; and the classification, eco-assessment of the wetland and landforms, and the dynamatic wetland landscapes; and the humane resources, humane landscapes and culture heritages. Especially we cmparative studied in the properties of wetland landscape and in the standards of world heritage.(2)wetland eco-tourism resources. On the basis of the assessment of the wetland plants, ancient tree and famous forest, waterfowl, we applied the digitalization principle and methods to study the wetland eco-tourism resources, and set up a mode and system of wetland landscape resource eco-assessment. Then, we divided the landscape into nine factors such as the wetland and landforms, the landscape water, the waterfowl and animals, the wetland plants, the value of wetland landscape aesthetics, appreciation and heritages, the wetland cultures, the value of wetland research and popularity, the ecological environment and tourist capacity, the tourism duration, condition and orientation.(3)eco-tourism value of wetland landscape resources. For a rational development and protection of the wetland, we studied its landscape resources and its value to created an assessment system of the ecological landscapes, and to evaluated qualitatively and quantitatively the value of wetland to the Eco-tourism. We also analyzed the structure, classification and order of the wetland landscapes. The results showed that South Dongting Lake Wetland satisfied the criterion of AAAA grade of China national scenic attraction. We studied and summarized as well the wetland landscape cultures resources, including the conception, function, classification and current situation of the wet-landscape culture in this region. It has been proved by the archaeologists that South Dongting Lake wetland was the center of the source of Dongting Lake, the cradle of Yangtze River civilization and origins of the Chu Culture. The results showed that the culture of South Dongting lake wetland was rich in diversity, those are the Rice Cultivation Culture, High-balustrade Dwelling, Nuo Culture, Ship Culture, Dragon Boat Culture, Chu Culture, Ancient Architecture Landscape, Wetland Foodstuff and Cuisine Culture, the Civil Art, the Historic Heritage and Cultural Relics, the Revolutionary Sitesand Ruins, and Production and Living Culture, etc, The Eco-tourism value of the landscape cultures in the region was discussed with emphasis, and we also analyzed its features and orientation. The results revealed that South Dongting Lake Wetland plays a key role on the Yangtze River reaches civilization, China civilization and even had a great influence on the global civilization. We summarized that the souls of the South Dongting Lake Culture were Wetland Culture, Water Culture, Riee Cultivation and Chu Culture. The thoughts, principles and approaches of sustainable utilization of the wetland landscape culture were formulated and were suggested,(4)eco-digitalization modeling of the wetland landscape resources. It also raised scientifically the eco-digitalization assessment standard system of wetl...
