| Aiming to the problems of flood and the characteristics of valley flood recently because of urbanization in our country, took the representative mountainous town valley (Zhuyou river) as studying object, using the basic theories and methods of landscape ecology, combining transdisciplinary and multifunctional landscapes studying, through the analysis valley landscape characteristics, with the relationships between configuration, form and function of landscape, to analyze thoroughly the characteristics of valley landscape, through the internal relationships between the characteristics of valley landscape and its hydrology ecosystem balance, from the angle of the safety of valley disaster prevention, to discuss the internal disaster prevention mechanism of characteristics of valley landscape, Then, based on the multifunction theory of landscape, analyze further landscape ecology synthesizes functions and its correlations. With the flood disaster investigates the analysis flood of representative mountainous town, realized that the main reason for increasing of valley flood is the damage of characteristics of valley landscape in town development. And also it is very important to protect the characteristics of valley landscape ecology, in order to keep sustaining and harmonious development. Last, lessoning from current studying about valley disaster prevention and landscape ecology protection in foreign developed countries, to discuss the harmonious ways for town developing. Through studying and analysis, find out that the orderly sustaining way for town developing lies in the harmonious relationship between Man and Nature, also understand and realized the characteristics and synthesizes functions of landscape ecology, demonstrated the relationship of configuration, form, function and location of valley landscape, this is the valid way to solve the problems in process of urbanization. |
