Abstract: Tourism economy has promoting and threatening effect on ecological environment, while ecological environment has bearing and restriction effects on tourism economy. Under the background of “harmonious coexistence between human being and nature” put forward by The 19th National Congress of the Communist Party of China, based on constructing an evaluation system for the coordinated development between tourism economy and ecological environment, this paper analyzed spatial-temporal characteristics of the coupling coordination degree between tourism economy and ecological environment in Heilongjiang Province from 2005 to 2015 by using the entropy approach and coupling coordination model. The results show the comprehensive evaluation function and comprehensive development index between tourism economy and ecological environment in Heilongjiang Province showed a rise in fluctuation, and the coupling coordination degree also showed a steadily upward trend during the study period, the coordination grade was gradually improved and there was closely coupling relation between tourism economy and ecological environment;in terms of spatial changes, there were obvious regional differences in the comprehensive evaluation function and the coordination status of tourism economy and ecological environment in different zones, the internal development gap is expanding for the uncoordinated regions,and there were little changes for the basic pattern of spatial evolution of coordinated development between tourism economy and ecological environment in each region of Heilongjiang Province. In general, although the coupling and coordination degree of tourism economy and ecological environment in Heilongjiang is increasing, the problem of interregional imbalance is still very significant. In order to realize the harmonious and symbiotic development of them, we need to take The 19th National Congress of the Communist Party of China spirits as guidance, and take positive and effective measures in setting up ideas, improving and implementing ecological protection system, promoting green development mode and life style.
