Spatial-Temporal Evolution Characteristics of NDVI in Middle and Lower Reaches of Lancang River Basin
Published 2022-01-01“…Vegetation coverage plays an important role in soil and water conservation,atmosphere regulation,and maintenance of ecosystem stability,which influences regional hydrological and water-sediment processes and has important implications for hydropower development in the basin.This paper analyzes the spatial and temporal evolution mechanisms of the normalized difference vegetation index (NDVI) in the study area from 1998 to 2018 using the Mann-Kendall model coupled with Sen's slope estimator,with the middle and lower reaches of the Lancang River Basin as the study area.The results reveal that ① the annual average NDVI in the study area from 1998 to 2018 is 0.81,and NDVI increases year by year from north to south on the whole;② NDVI in the study area shows an insignificant increasing trend from 1998 to 2018,with a growth rate of 5.8 × 10<sup>-3</sup>/a;③ the sudden spatial changes in NDVI all occur in degraded areas.Against the background of increasing global warming and the frequent occurrence of extreme weather in the past two decades,the results of this study provide a scientific basis for future biodiversity conservation and ecological and environmental protection in the Lancang River Basin.…”

Application of Combined Multiple Linear Regression Model in Runoff Prediction
Published 2021-01-01“…In order to improve the hydrological prediction accuracy,a shuffled frog leaping algorithm (SFLA)-combined multiple linear regression (CMLR) runoff prediction model is proposed.This paper first builds a CMLR model based on principal component analysis (PCA) data with and without dimensionality reduction;then optimizes the CMLR constant term,partial regression coefficient and combined weight coefficient by the SFLA to establish a SFLA-CMLR runoff prediction model;finally apply the SFLA-CMLR model on two examples of annual runoff prediction,and establishes the SFLA-PCA-MLR,SFLA-PCA-SVM (support vector machine),(least squares) LS-PCA-MLR,PCA-SVM,with dimensionality reduction of PCA,as well as SFLA-MLR,SFLA-SVM,LS-MLR,SVM,without dimensionality reduction as comparative prediction models.The results show that the average relative error of the SFLA-CMLR model for the annual runoff prediction of the two examples is 1.54% and 4.63%,respectively,and the prediction accuracy is better than that of SFLA-PCA-MLR and other 8 models.Therefore,it has better prediction accuracy and generalization ability.…”

Cause Analysis and Control Measures of Waterlogging in Shanghai Zoo Based on MIKE 21
Published 2023-01-01“…In order to analyze the cause of waterlogging after the drainage system of Shanghai Zoo reached the standard and explore the best control measures,data analysis and field investigation were carried out,and it was preliminarily determined that the waterlogging in the zoo was related to the poor drainage of the water system and the insufficient drainage pumping station.MIKE 21 was used to build a hydrodynamic model of the water system in the zoo,and the changes in the hydrological characteristic values of the water system under the current drainage condition were simulated and studied.It is concluded that the root cause of waterlogging in the zoo is that the drainage path is blocked,and the drainage pumping station has an insufficient scale and unreasonable layout.In order to promote drainage and remove waterlogging,the water system optimization and waterlogging facility renovation plans were proposed,and the engineering effect of each plan was simulated.Through the comparison of indicators such as drainage rate,drainage time,and maximum drainage time difference in different regions,the effect of each plan in promoting drainage and removing waterlogging was determined.In view of the engineering economy,the plan of expanding culverts and moving some culverts to the river was determined as the best,and the drainage layout was adjusted to achieve the best control effect under the specific investment.…”

Application of HEC-HMS Model in Flood Simulation of Qingshan River Basin
Published 2021-01-01“…It is more and more important to realize the fast simulation of flood process in the early warning of mountain flood disaster in small and medium river basins.This paper builds a distributed hydrological model for Qingshan River Basin by combining HEC-HMS model with GIS technology,extracts the characteristics of river system and conducts gridding on small basin based on DEM data,calculates the surface runoff by initial and constant loss method and Snyder unit hydrograph method,simulates the process of base flow recession through nonlinear boussinesq method,conducts the channel routing by Muskingum method,calibrates the parameters with the past 5 measured flood data,as well as verifies the prediction results by 13 floods.The simulation results show that during the verification period,the errors of peak discharge are all within 20%,the time difference for peaks is less than 3 h,the certainty coefficient is less than 0.7 for only 2 floods,and above 0.7 for others.The results show that with high accuracy and stability,the HEC-HMS model for flood simulation in this river basin conforms to the requirements of the flood forecast,which is of great application value for the exploration of small basin flood simulation and analysis.…”
