The Research On Tourism Resort Landscape Ecological Evaluation Based On GIS

Landscape ecological evaluation is the premise of understanding landscape correctly,protecte effectively and develop reasonable to utilize the landscape resources and promote the sustainable development,which also is the strong basis for landscape planning,management and protection.The introduction of landscape ecology theory and GIS technology into the planning and construction of tourist resort is the inevitable trend of the current tourism resort development.The paper constructs a set of modern landscape ecological evaluation system of tourist resort based on GIS,and provides guidance for the realization of tourism resort from traditional extensive to ecological continuous transformation.The main results of the study are as follows:Combing and summarizing the related concepts of tourism resort,landscape ecological evaluation,GIS and the theoretical basis of landscape ecological planning,and analyzes the research status of the tourism resort,landscape ecological evaluation and GIS technology in landscape ecology evaluation,which lays a theoretical foundation for the future research.On the basis of analyzing the relevant theories of traditional and modern landscape ecological evaluation system,selecting six degree of the landscape originality,landscape compatibility,landscape sensitivity,landscape suitability,landscape connectivity and landscape health from the modern landscape ecology evaluation as the tourist resort evaluation criteria layer.In terms of landscape originality,obtaining the grading map and distribution of the original degree through evaluation analysis the three level of the primary,semi-native and artificial landscape.In terms of landscape compatibility,obtaining the grading map and distribution of the landscape compatibility degree by constructing the matrix judgment and calculating the degree of compatibility of the landscape types of the whole behavior system of the resort based on the compatibility formula.In terms of landscape sensitivity,selecting the four factors of the relative slope,relative distance,visual probability,eye-catching degree one by one to analyze the measurement based on GIS,and then obtain the grading map and distribution of the landscape sensitivity.In terms of landscape suitability,seclecting the six factors of height,slope,slope direction,water cushion,land type and air negative ion concentration to obtain grading map and distribution of the landscape suitability.In terms of landscape connectivity,selecting the ecological connectivity index and obtaining the grading map and distribution of the landscape connectivity based on the minimum cost distance model.In terms of landscape health,the normalized vegetation index,landscape diversity index,ecosystem service function value and ecological elasticity were selected to obtain the comprehensive evaluation and distribution of health degree by weighted superposition.Finally,obtaining the comprehensive distribution of landscape ecological evaluation by weighting these six degrees based on GIS.Based on the evaluation results of the tourism resort in Jiaoyan of Yanshan county,establishing a hierarchical protection area respectively including the six degree of the landscape originality,landscape compatibility,landscape sensitivity,landscape suitability,landscape connectivity and landscape health,Then superimposing and analyzing the six degree to establish the hierarchical protection area,the area of primary,secondary and tertiary protected areas was 155.38hm~2,185.97hm~2 and 198.04hm,respectively,and the percentages of the resort were 28.81%,34.48%,36.72%.And put forward the relevant countermeasures and suggestions of the landscape ecological planning and tourism development according to the evaluation result and the present situation.
