Abstract: With the ecology principle as the standard, the computations of forest park ecology capacity, forest ecology value as　well as ecology trail helped the authors to systematically analyse Jingyue Tan forest park ecology function and sustainable development strategic objective and to indicate the tour population of Jingyue Tan forest park at present still slightly lower than the ecology capacity.
