[Objective] The aim was to establish a model based on spatial scene similarity, for which soil, slope, transport, water conservancy, light, social economic factors in suitable planting areas were all considered. A new suitable planting area of flue-cured tobacco was determined by comparison and analysis, with consideration of excellent area. [Method] Totaling thirty natural factors were chosen, which were clas- sified into nine categories, from Longpeng Town (LP) and Shaochong Town (SC) in Shiping County in Honghe Hani and Yi Autonomous Prefecture. [Result] According to weights, the factors from high to low were as follows: soil〉light〉elevation〉slope〉 water conservancy〉transport〉baking facility〉planting plans over the years〉others. The similarity of geographical conditions in the area was 0.894 3, which indicated that the planting conditions in the two regions are similar. If farmer population in unit area, farmland quantity for individual farmer, labors in every household, activity in planting flue-cured tobacco and work of local instructor were considered, the weights of different factors were as follows: farmer population in unit area〉farmland quantity for individual farmer〉farmers' activity in planting flue-cured tobacco〉educational back- ground〉labor force in every household〉instructor〉population of farmers' children at- tending school. The similarity of geographical conditions was 0.703 1, which indicated that it is none-natural factors that influence yield and quality of flue-cured tobacco. [Conclusion] According to analysis on suitable planting area of flue-cured tobacco based on assessment of spatial scene similarity, similarity of growing conditions in two spatial scenes can be analyzed and evaluated, which would promote further exploration on, influencing factors and effects on tobacco production. 展开更多

In order to improve the recognition accuracy of similar weather scenarios(SWSs)in terminal area,a recognition model for SWS based on contrastive learning(SWS-CL)is proposed.Firstly,a data augmentation method is designed to improve the number and quality of weather scenarios samples according to the characteristics of convective weather images.Secondly,in the pre-trained recognition model of SWS-CL,a loss function is formulated to minimize the distance between the anchor and positive samples,and maximize the distance between the anchor and the negative samples in the latent space.Finally,the pre-trained SWS-CL model is fine-tuned with labeled samples to improve the recognition accuracy of SWS.The comparative experiments on the weather images of Guangzhou terminal area show that the proposed data augmentation method can effectively improve the quality of weather image dataset,and the proposed SWS-CL model can achieve satisfactory recognition accuracy.It is also verified that the fine-tuned SWS-CL model has obvious advantages in datasets with sparse labels. 展开更多

Industrial tourism has become a new hot spot for tourism development at home and abroad, but there is still no clean energy industry tourism in Xinjiang. Combined with dabancheng scenic spots planning cases, this paper analyze the conditions for the comprehensive development, the overall concept and industrial tourism products design and other aspects, which draw conclusions that integrated area planning should highlight the characteristics, focus on the aspects of comprehensive development, market positioning and other in-depth study. 展开更多

As a new tourism pattern, red tourism develops rapidly in China. In Shandong, not only the red cultural heritage is rich, but also the red tourism resources are rich, but the development is not very successful now. The paper aims at surveying the status of Shandong red tourism, and analyzes the evaluation of tourists on red tourist attractions by the way of market research. The research indicates that red tourism has the problems including improper publicity, single development model and imperfect infrastructures, for which the paper proposes the suggestions such as multi-channel publicity and multi-mode development. The research results of the paper not only provides scientific basis for developing red tourism in Shandong, but also provides reference for practical management on red tourism. 展开更多

Mining activities may cause serious damages to the river ecological environment in mining areas. It has been realized that challenging is faced for optimal decision-making on the river ecological restoration resulting from system complexity, multi-objectives, long term restoration in which multiple stages may be needed to take, and difficulty in detailed process quan- tification. By analyzing and fully reflecting the differences between the central zone and surrounding zones of the restored river passing through the mining area, the comprehensive evaluation index systems of the central zone and surrounding zones are separately suggested firstly. Then a scenario-based optimization decision-making model for river ecological restoration in min- ing areas was established with taking advantages of spatial divisions and following procedure of first going through optimiza- tion by sub-region level, then optimizing by integration. Then, a framework for scenario-based optimal decision-making on water-deficient river ecological restoration in mining areas is proposed in which a multi-objective and multi-stage spatial division optimization method is considered to improve decision-making efficiency and enhance its practicability. It is indicated that this optimization framework is reasonable and practical, which is expected to offer reliable decision support in identifying the effective solutions on optimal management of the water-deficient river ecological restoration in mining areas. At the same time, it has implications in general land reclamation and ecological restoration in the mining areas. 展开更多

There is a great potential of both supply and consumption in oil & gas market in Northeast Asia, and the prospects of further cooperation is very broad. Sino-Russia cooperation on oil & gas will lay a crucial foundation for building a regional oil & gas market, and an increasingly opened trading system for oil & gas will also meet Japan and South Korea's need in building a diversified and stable assurance system of oil & gas supply. The strategic role played by Kozmino Port in Far East Russia and Shanghai oil and gas trading platform in China will be highlighted. Competition and cooperation through market mechanism will help to activate the interactions of resource flow and capital flow in Northeast Asia region, thus can also help energy consuming countries in the region to promote their disclosure power in global pricing system and gradually eliminate the Asian Premium. 展开更多
