    During seed germination，seven different concentrations of NaCl solution（0. 5，1. 0，2. 0，3. 0，5. 0，7. 0，9. 0 g/L）were used to study the response of three different varieties of kidney beans under NaCl stress. All the three varieties of kidney beans showed the trend that high concentrations of NaCl solution decreased seed germination rate，germination potential，germination index，vigor index，root length，bud length，lateral root number，fresh weight，SOD activity while increased the MDA content of seedlings. However，the effects of low concentrations on seed germination index， seedling growth index and physiological index were related to the concentration of NaCl and the variety of kidney bean. The results of comprehensive evaluation of membership function showed that the salt tolerance of the three varieties was in the order: safflower white kidney bean > Xiza 2 (wide) kidney bean > Xiza 2 kidney bean.

    The effects of different concentrations of auxins IBA（indole butyric acid）， NAA（naphthalene acetic acid）and cytokines 6-BA（6-benzyl adenine），KT（kinetin）on the induction of adventitious buds and roots were studied from the cotyledonary node of "Bean white rice" common bean，and the common bean′s tissue culture seedlings were cultivated and transplanted. The results showed that the optimum medium for buds induction was MS + 1. 0 mg/L IBA + 0. 5 mg/L 6-BA + 0. 1 mg/L KT，the cofficient of the bud differentiation was 2. 89. The optimum rooting medium was MS + 0. 1 mg/L IBA，the rooting rate was 100%. The common bean′s tissue culture seedlings can survive after transplanting.

    In order to solve the problem of the shortest path with weight under complex network conditions，a tabu search algorithm based on compression graphs was proposed. With the constraintbased graph compression algorithm，the weighted shortest path problem under complex constraints was transformed into travelling salesman problem（TSP），and the optimization of the tabu search algorithm was used to solve the weighted shortest path problem under complex constraints. The simulation results showed that the tabu search algorithm based on compression graph had the advantages of fast solution，low time complexity，fast convergence，and insensitivity to graph scale and constraint conditions.

    Based on the theory of dissipative structure，the formation mechanism of the dissipative structure of the ice and snow sports industry in China and its self-organizing development path were analyzed under the background of the continuous evolution of the ice and snow sports industry from "organized" to "self-organizing". The results show that keeping the openness is the prerequisite for the formation of dissipative structure in the ice and snow sports industry in China，and keeping away from the equilibrium state is the necessary condition for the formation of the dissipative structure in the ice and snow sports industry in China. Nonlinear interaction is the internal basis of the formation of dissipative structure in China′s ice and snow sports industry and the fluctuation mechanism is the development basis of the formation of dissipative structure of China′s ice and snow sports industry. On the basis，combined with the current situation and existing problems，this paper puts forward some reasonable suggestions on optimizing the self- organizing development path of ice and snow sports industry.

    The influence factors on the ice and snow sports tourism industry were analyzed with the Delphy method，it was found that the main factors included the expansion of consumption，the training of professionals，government policy，technology and product development. This paper used the analytic hierarchy process （AHP） structure model for ice and snow sports tourism industry development， to analyze the weight and index of correlation matrix. The results showed： the influencing factors on the development of ice and snow sports tourism industry contained four first level indicators，including“expanding consumer”accounted for the maximum weight；13 second level indicators，of which the“ski facilities”and“ski coach training”had high weight. According to the order of weight value，some suggestions were put forward to promote the development of ice and snow sports tourism industry in China.
