Abstract:By experiment and observation on the spot, the impact of tourist and recreational activities on meadow seeds germination rate of Medicago sativa and Trifolium repens in the Langya mountain scenic area was analyzed. The results showed: (1) the seed germination rates of two kinds of plants were negatively linearized a correlated with the strength of tourist and recreational activity. In three tour route experimental groups: the long range, the medium range and the short range, the seed germination rates of Medicago sativa were in sequence of 31.29%, 39.41% and 55.21%, and the rates of Trifolium repens were of 8.42%, 14.62% and 23.89%. The more distant the experimental group is from the tour route, the higher the seed germination rates are. There were significant differences of the rates between the farthest group from the tour route and the nearest one. (2) In four other patterns of the tour route experimental groups: asphalt, cement, step and soil, the seed average germination rates of Medicago sativa were in sequence of 37.20%, 40.27%, 41.28% and 4813%, and the rates of Trifolium repens were of 10.37%, 10.92%, 14.23% and 27.05%. The seed germination rates of tour route experimental region with less tourism and recreational activities were higher than those of the region with more tourism and recreational activities. Moreover, the seeds germination rates of the two observed plants were significantly different in the same experimental route and place.
