    Study on Ecological Security Assessment of Dongjiang River Basin in Jiangxi Province Based on PSFR Model by LIU Huili, ZHA Dongping, FENG Minglei, WAN Ying

    Published 2021-01-01
    “…In order to find out the ecological security situation of Dongjiang River Basin in Jiangxi Province,and formulate targeted ecological protection measures for protecting the clear water of the Dongjiang River,this paper determines the weight of indexes through the “Pressure-State-Function-Risk”(PSFR) model and analytic hierarchy process (AHP),establishes and optimizes the ecological security assessment system of Dongjiang River Basin in Jiangxi Province,and combines with “3S” technology and expert support system to evaluate the ecological security of Dongjiang River Basin in Jiangxi Province.The results show that:The ecological security index (ESI) of Dongjiang River Basin is 74.80,and the ecological security state of the Dongjiang River Basin is relatively safe.The main environmental problems in the river basin are the disconnection of the river system,the failure of the water environment quality to reach the standard,the reduction of the aquatic biological resources and diversity,etc.The severe human activities,the high density of hydraulic structures,the potential pollution of mining and orchard development,the degradation of important habitat area,the degradation of wetland area and the weakening of watershed ecological service function are the causes.On the basis of the assessment,the main factors affecting the ecological security of the river basin are put forward in this paper,which provides technical basis for the formulation of the next protection plan,and the index system has a strong reference significance to the fine management of ecological risk control in other basins.…”

    Runoff Forecasting Research Coupling Quadratic Factor Screening and Deep Learning by CHENG Liwen, HUANG Shengzhi, LI Pei, LI Ziyan, JIA Songtao, HUANG Qiang

    Published 2023-01-01
    “…The effective screening of factors influencing runoff is a key aspect of runoff forecasting research.However,there are many factors affecting runoff,and these factors have complex interactions.Most of the existing studies use numerically driven models with primary factor screening,and the results show that the input factors are spatially redundant,leading to poor forecasting results.In view of this,the support vector regression (SVR) and the long-short memory network model (LSTM) are compared with Weihe River Basin as an example,and the LSTM model is selected as the optimal forecasting model.Principal component analysis and gray correlation analysis are used for secondary screening of the input terms to form a model coupling principal component analysis,gray correlation analysis,and LSTM.The results show that:①the fitting accuracy of LSTM is higher than that of SVR;②the secondary screening of the input terms improves the forecast accuracy,and the forecast accuracy of the coupled model is better than that of the single model,specifically,the model accuracy evaluation indexes of the coupled model are substantially improved compared with those of the single model;③the Nash efficiency coefficient and deterministic coefficient of the coupled model of gray system correlation analysis are improved by 0.13% and 0.03%,respectively,compared with those of the coupled model of principal component analysis,and the standard deviation ratio of observed values is improved by 42.9%.The study shows that the secondary factor screening by using gray correlation can effectively improve forecast accuracy.…”
