Application Prospect of Big Data Technology in the Informatization of Soil and Water Conservation by LUO Wen, LIU Xing, YUAN Zaijian

“…Soil and water conservation is an important part of China's environmental protection work.The construction and application of big data of China's ecological environment have brought technological innovation to soil and water conservation work.However,the application of big data technology in the informatization of soil and water conservation is still in the exploratory stage,and the technology is only used in the soil and water conservation monitoring and construction project guidelines.This paper briefly discusses the informatization construction of soil and water conservation in China.It prospects for the application of big data technology in the design,scheme preparation,monitoring,supervision and management,acceptance evaluation,treatment informatization of soil and water conservation and soil erosion forecasting combined with the processing systems such as batch data,streaming data,interactive data and graph data and the analysis techniques such as knowledge calculation and in-depth learning. Finally,given the deficiencies and difficulties in soil and water conservation informatization, some suggestions are put forward,such as strengthening informatization construction,building data collection standards, establishing soil and water conservation knowledge base,and cultivating the talents in the field of big data of soil and water conservation,providing a reference for accelerating the informatization of soil and water conservation.…”

Study on Hydrological Drought Forecasting Based on SWAT Model and ESP Thought by SUN Long, LI Meng

“…Based on measured data such as 40-year long series of hydrological and meteorological data from 1970 to 2009,and the distributed hydrological model SWAT with strong mechanism and integrated forecasting ESP thought,this paper builds a set of drought forecasting system,optimizes the parameters of SWAT model by data from 1970 to 2009,predicts the future long-term (April to October,2010) hydrological drought in the middle and lower reaches of Ganjiang,and calculates and predicts the probability of occurrence of hydrological drought from early April 2010 to late October 2010 in a ten-day basis with ten-day runoff depth anomaly percentage as the early warning indicator for judging the hydrological drought in various districts and counties.The results show that,hydrologic drought is more likely in the middle of May,middle of June to late July,middle of August,early September and middle of October to late October, among which a wide range of hydrological drought is likely to happen in early to middle of July and middle to late October.The predicting results can provide scientific guidance for drought resistance and disaster reduction.…”

Shuffled differential privacy protection method for K-Modes clustering data collection and publication by Weijin JIANG, Yilin CHEN, Yuqing HAN, Yuting WU, Wei ZHOU, Haijuan WANG

“…Aiming at the current problem of insufficient security in clustering data collection and publication, in order to protect user privacy and improve data quality in clustering data, a privacy protection method for K-Modes clustering data collection and publication was proposed without trusted third parties based on the shuffled differential privacy model.K-Modes clustering data collection algorithm was used to sample the user data and add noise, and then the initial order of the sampled data was disturbed by filling in the value domain random arrangement publishing algorithm.The malicious attacker couldn’t identify the target user according to the relationship between the user and the data, and then to reduce the interference of noise as much as possible a new centroid was calculated by cyclic iteration to complete the clustering.Finally, the privacy, feasibility and complexity of the above three methods were analyzed from the theoretical level, and the accuracy and entropy of the three real data sets were compared with the authoritative similar algorithms KM, DPLM and LDPKM in recent years to verify the effectiveness of the proposed model.The experimental results show that the privacy protection and data quality of the proposed method are superior to the current similar algorithms.…”

Distributed trust management scheme based on blockchain in Internet of vehicles by Haibo ZHANG, Yukun CAO, Kaijian LIU, Ruyan WANG

“…Aiming at the security problems caused by the low efficiency and accuracy of malicious vehicle identification in Internet of vehicles, a distributed trust management scheme based on blockchain in Internet of vehicles was proposed.A false information identification strategy was designed by aggregating the scoring information of vehicles, combined with Bayesian inference model.A reputation value updating algorithm was designed by combining the historical interaction information of vehicles and traffic information, malicious vehicles were identified by the reputation threshold.A blockchain was constructed roadside units to realize the distributed storage of traffic data and vehicle reputation values.The traditional proof of work consensus mechanism was improved to dynamically change the difficulty of miner node generating a block through the event level and the number of vehicles involved in scoring, and the waiting mechanism was used to temporarily stop the nodes that had recently blocked from participating in the election process of miner nodes, thus reducing the resource consumption caused by repeated calculations.The simulation results show that the proposed scheme can effectively identify false information, resist the deceptive behavior of malicious vehicles, improve the identification efficiency of malicious vehicles, reduce resource consumption, and is effective and feasible in distributed trust management for Internet of vehicles.…”
