Due to huge disaster-caused force, seismic geological disasters primarily induce residual landslide, collapse and debris flow disasters with far higher hazard extent than that of earthquake disasters. Wherefore, this paper, with various vibration slopes caused by the most representative Wenchuan earthquake as research objects, introduces the strength reduction method to the stability study of residual mountains in a certain area, puts forward dynamic stability slope evaluation method based on dynamic and overall strength reduction method to obtain the mountain slope stability situation in the process of gradual instability, searches out the sliding surface of progressive expansion making use of dynamic strength reduction method and calculates dynamic safety index in the process of gradual slope instability pursuant to the calculation advantages of dynamic strength reduction method, so as to realize the analysis and regulation of the whole process of slope instability. The results show that in the stability analysis of a homogeneous slope, the safety index of slope stability calculated by strength reduction method is 6.7%, 8.8% and 10.5% higher than that calculated by finite element limit equilibrium method, Bishop method and Janbu method respectively. In the stability analysis of a multi-layer soil slope, the safety index of slope stability calculated by strength reduction method is 4.8%, 4.3% and 9.4% higher than that calculated by other three algorithms. While in the stability analysis of soft interlining slope, the safety indexes of slope stability calculated by the method proposed in this paper are increased by 26.10%, 29.11% and 26.46% respectively compared with other three algorithms, indicating that the stability of landslide residual mountains calculated by strength reduction method proposed in this paper is the highest.

“…In order to verify the ecological management effect of the system on the region, the ecological function of the forest region is evaluated from four aspects [28][29][30][31]: plant biomass, organic carbon storage, nutrient accumulation, and water retention capacity. The contents of different components were determined, and the first-order index of ecological function was measured using average value method [32][33]. Assuming that the actual measured value of the secondary index of sample plot is , and the mean value and standard deviation of the secondary index among all sample plots of the same factor are and respectively, the calculation formula for the score of the secondary index of sample plot is as follows: (12) Thus, the ecological functional comprehensive index of each level index can be deduced: (13) Where, is the number of all second-level indicators contained in plot .…”

Plantations play a central and lever role in maintaining the ecological balance of the earth, maintaining the overall function of the terrestrial ecosystem, and promoting the coordinated development of economic society and ecological construction. In order to strengthen the ecological management of plantation forests and improve the ecological level of forest region, the C/S framework is taken as the basic structure, and the programming mode of business model-user interface controller is used, on J2EE platform. The ecological management system of a planted forest is constructed by the evaluation module, the principal component comprehensive analysis module of ecological function value and the demand prediction module of planted forest based on extreme learning machine and deep learning algorithm, and runs under the support of windows system, oracle 15G and above database software. The indexes and factors affecting the ecological function of plantation forests were evaluated and analyzed, and the final management decision was given by the prediction module. The results showed that the plant density significantly affected plant biomass, organic carbon storage, water content and nutrient accumulation, and the comprehensive evaluation indexes of four ecological functions increased from 32.69, 31.84, 33.71 and 35.46 to 86.18, 89.46, 89.83 and 88.76, respectively. Although the degree of influence of the system on lemon strip plants, herbaceous plants, surface litter and soil varies, it still has good feasibility, effectiveness and practicality, and can assist the scientific ecological management of artificial plantation forests.

The increasing pollution caused by carbon emissions has led to a growing call for emission reduction. With China's current goal of carbon neutrality, how to innovate the petrochemical industry has become a hot issue. As a higher education institution that delivers talent for the petrochemical industry, it is in line with this trend to carry out teaching reforms of professional courses. In this paper, we collect data extensively for the evaluation of course attainment in the petrochemical industry and carry out the weight allocation of factors. Two classes of a university's 2018 class of petrochemical industry majors were used as the comparison objects. One of the classes was taught in a reformed manner while the other class was taught in a traditional manner. The results showed that the overall score of the class subjected to reformed instruction was 78.9, which was greater than the 74.6 score of the class taught using the traditional approach. In addition, when surveyed for feedback on course content, it was found that a whopping 92% of students showed identification with their major. Only 2% of the students felt that the new teaching style was a waste of their time.
