Impact Of Tourism Stampede Behavior Martial Mountain Meadow

In order to understand the influence of tourism on Wugong Mountain mountain meadow, based on the study at home and abroad on the basis of tourism disturbance on the meadow on the influence, in the scenic area without trampling disturbance are set in the 3experiment plots, a comprehensive selection of meadow, meadowvegetation coverage,plant height, number of species, the dominant species and companion species the total number of 6 indexes to investigate the effect of recreation activities on Wugong Mountain mountain meadow, and calculated the standard deviation of each index. In addition by using GM(1, 1) modeling method to build the Wugong Mountain scenic area "trampling intensity and vegetation coverage" relationship model, trampling intensity and vegetation coverage correlation calculation based on this model, calculated the change range of scenic vegetation in the stampede jamming, and calculate the scenic Wugong Mountain stampede interference resistance and vegetation analysis of the recovery by the analysis of variance.The main results are as follows:(1) with the increase of the Wugong Mountain scenic area on the intensity, vegetation height and relative decline in coverage, vegetation height and coverage of standard deviation decreases. If the pedal interference continue to strengthen, vegetation height and coverage tends to be uniform, the Wugong Mountain scenic area of horizontal structure and vertical structure of vegetation change.(2) with the increasing intensity of trampling disturbance, meadow plant species number did not change the number of species, but sometimes increase and sometimes. But the stampede will adversely affect the structure of the species, dominant species and companion species led to the increase in the number of, this is because the number of dominant species decline or extinction of species causing a stampede, and seize the opportunity to continue to expand the advantage, companion species in human activity is strong, so the increase number of companion species with the strengthening of trampling intensity.(3) analysis showed that the tread test, even low intensity of stampede will have an impact on the meadow species, 2 months after the end of the tread and trample, strength is higher than 200, influence still exists.(4) the GM(1, 1) model constructed by the method of "trampling intensity vegetation" model better reflects the Wugong Mountain mountain meadow of the relationship between the 2, and the error was within 10%, the accuracy meets the requirements, GM(1,1) model can be better applied to the trampling intensity and the relationship between vegetation coverage.(5) The fifth chapter of this paper by Wugong Mountain mountain meadow vegetation coverage are 2 threshold of tourism trampling disturbance intensity: 313 times(relative reduction of 24% vegetation coverage) and 683 times(relative reduction of 32% vegetation coverage). When trample intensity is lower than 313, vegetation coverage change relatively gentle; trampling intensity change is relatively stable in the 313 and 683 times;when the trampling intensity more than 683 times, plant coverage at a faster rate reduction.When trample intensity is lower than 313, the Wugong Mountain mountain meadow vegetation coverage and the average height of dominant species changed little, but compared with the number of companion species not stampede bands changed greatly.(6) after the end of the Wugong Mountain stampede, mountain meadow vegetation relative coverage gradually recovered, the recovery speed from slow to fast, 2 months after the end to stampede, average relative coverage recovered to 78.5%.
