In this paper, the generalizedG′G-expansion method is used to construct exact solutions of the (2+1)-dimensional Boiti-Leon-Pempinelli system. As a result, non-travelling wave solutions with arbitrary functions are obtained including hyperbolic function solutions, trigono-metric function solutions and rational solutions. If the parameters take different values, some more solutions are derived. It is shown that the generalizedG′G-expansion method, with the help of symbolic computation, provides an effective and powerful method for solving high-dimensional nonlinear partial differential equations in mathematical physics.

The fractional Logistic chaotic map has a simple form but holds complex dynamic behavior and can be readily generated on computer. In this paper, an image encryption algorithm is proposed by using the map and DNA coding. The fractional chaotic map generates a key chain. Each pixel layer of the RGB image is encrypted through changing pixel locations. A gray scale image is obtained by combination of the three encryption results. The encrypted image not only changes the size of the original image but the type. Through the security analysis including key sensitivity, statistics and correlation analysis, the results show that the algorithm has good robustness, key sensitivity and enhanced the key space and leads to high security.

Rice particle adhesion in rice detection process brings great difficulties to subsequent rice detection and classification. In this paper, a method of segmentation of adhesion rice based on concave point matching is presented. Firstly, the original image is preprocessed based on the feature of Rice image combined with the thought of morphology. Second, the original image is preprocessed by using chain code tracking to calculate the curvature of the image boundary after segmentation, and then search the concave point according to the curvature result and chain code difference. At last, the concave point is matched, and the concave point is connected with the dividing line. The concave point matching segmentation is realized. The experimental results show that the method has better segmentation effect than traditional segmentation method, and can effectively restrain the segmentation phenomenon.

In order to realize the low carbon development of the city, it needs the cooperation of the city residents. The study on the residents’ energy use behavior in Zunyi city is conducted by means of random distribution of questionnaires and statistical data obtained by spss19.0. The research shows that the average value of the residents' energy use behavior in Zunyi is between 3.15~3.65, which shows that the energy conservation awareness is not strong. The residents’ energy use behavior is significantly and positively related to the psychological factors of residents, external situational factors, gender, age and education level. According to the research, policy recommendations are put forward for the development of low-carbon economy in Zunyi: raise awareness of residents’ energy use behavior| increase publicity and education of energy conservation| constrain the residents’ energy use behavior through policy and social norms.

To evaluate the soil erosion in Panzhou City, and to provide scientific basis for soil erosion control and land use decision. Based on GIS and modified RUSLE model, the daily rainfall of 12mm and 30mm for the erosive precipitation from the value of the use of 2000 to 2015, Panzhou City, NDVI, DEM, daily rainfall, soil and land use data to calculate the soil Erosion modulus. In the karst area, the traditional method will overestimate the total amount of soil erosion, so the improved rainfall erosivity is more in line with the local situation. The average erosion modulus in 2000 is 67.97t ha^-1yr^-1 and 23.33 in 2015 t ha^-1yr^-1| soil erosion intensity grade transfer matrix shows that most of the soil erosion intensity to a lower level of transfer, the city's soil erosion grade showed a downward trend. In the analysis of soil erosion and slope, the erosion grade is mainly concentrated in the gentle slope and the steep slope| and in 2015 the erosion rate in the steep slope of the rapid decline, which in recent years to promote ≥25° slope of all the policy of returning farmland to forest| But the slope steep valley deep area and the surrounding area of urban construction area is still the focus of future soil and water conservation.

According to the basic connotation of decoupling theory, this paper calculates the decoupling elastic coefficient D of Yunnan province's economic development and water resources pressure by using the data of water resource utilization rate and GDP growth rate from 2005 to 2015, and divides the decoupling status of water resources utilization and economic development during the study period according to economic development and water resources pressure decoupling state division standard, and then evaluates their decoupling states. The research shows that: from 2005 to 2015, the economic development of Yunnan province continued to grow| the water consumption growth rate shows the fluctuating state characteristics during the study period, and the water consumption is decreasing| in the change feature of the decoupling elastic coefficient D, D value is given priority to with negative values, and the research period D values are smaller. Under the current situation of economic growth in Yunnan, the economic development and the utilization of water resources show a good decoupling. In the change of the decoupling state, the characteristics of the two states——strong decoupling and weak decoupling——are presented. In terms of decoupling state composition, the strong decoupling counts for 63.6%, which showed a strong decoupling trend. It indicates the growth of yunnan's economic output, while the use of water resources is decreasing, and its economic development and water resources utilization show a more harmonious relationship. According to the research results, this paper puts forward some countermeasures and suggestions to optimize Yunnan's economic development and water resources utilization.
