The Healthy Riparian Zone And Its Evaluation Method Research In Liao River Reserve

Nowadays, the concept of healthy riparian zone is not clear enough, evaluation methods isconfused, and the evaluated standard is not unified, then the study of healthy riparian zone isimminent. In this paper, we took Liao River reserve as the object, and collected and summarizedthe definition and the connotation of river riparian, and riparian zone evaluation methods athome and abroad, and then we made certain of the basic concept of healthy riparian zone.According to the concept of that, we used the method named PCA to choose the specific indexabout the healthy riparian zone’s index system, and then, we determined the standards, too. Upto the research about the evaluated methods to the river riparian zone, we have chosen threemethods named Fuzzy, Approaching Degree and Cluster Analysis for screening the evaluationmethod. At the same time, we made a research about healthy riparian zone in Tieling beach ofLiao River reserve and we used the data and statistics to verify the evaluation method at presentstage in Tieling beach of Liao River reserve.1、After collecting the definition and evaluation methods both at home and abroad, wehave defined the meaning of healthy river riparian zone, heve built the evaluation index systemand the evaluated standard.2、After making a match of the basic principles, theoretical basis, applicated conditions,advantages and disadvantages preliminarily, we have chosen the evaluation methods forscreening, they are Fuzzy, Approaching degree, clustering methodology.3、We have taken the use of the test data, gotten the result by applying to screeningevaluation methods, and put forward a concept named deviation degree coefficient whichcomanied with the fitness of reality to determine an evaluation method for Liao River reserve.This suitable method should be approaching degree which has been testified by the evaluationof Tieling beach in Liao River reserve and we have known that the condition of the healthyriparian zone of Tieling beach in Liao River reserve is fine.
