【摘要】：利用省際面板數(shù)據(jù),從全國及區(qū)域?qū)用嫜芯啃略鏊顿Y、各類型水利設施在抗擊農(nóng)業(yè)旱災、水災中的效果。研究發(fā)現(xiàn):從全國層面看,新增水利投資能有效降低旱災成災率、水災成災率,但水利投資抗旱效果比抗擊水災效果好。水庫能有效抗旱,但加重了水災成災率,水閘抗旱效果明顯。從區(qū)域?qū)用婵?東、中、西部地區(qū)水利投資抗旱效果都較明顯,而水利投資抗御水災效果東部地區(qū)最明顯。機井在中部地區(qū)對抗旱起到了一定作用,但東部、西部地區(qū)機井數(shù)量卻與旱災成災率正相關。水閘抗御水災的作用在中部地區(qū)顯著。中部地區(qū)堤防長度與水災成災率正相關,西部地區(qū)機電排灌站裝機容量與旱災成災率正相關。東部地區(qū)機電排灌站裝機容量與水災成災率負相關,而在中部地區(qū)兩者正相關。
[Abstract]:Based on the data of interprovincial panel, this paper studies the effects of new investment in water conservancy and the effects of various types of water conservancy facilities in the fight against agricultural drought and flood from the national and regional levels. It is found that the new investment in water conservancy can effectively reduce the rate of drought disaster and flood disaster, but the effect of water conservancy investment is better than that of fighting flood. The reservoir can resist drought effectively, but the flood disaster rate is increased, and the drought resistance effect of sluice is obvious. From the regional level, the effects of water resources investment on drought resistance in the east, middle and west regions are obvious, while the effect of water conservancy investment on flood resistance is the most obvious in the eastern region. The number of wells in the eastern and western regions is positively related to the rate of drought disaster. The flood resistance of sluices is significant in the central region. The length of embankment in the central region is positively correlated with the flood disaster rate, and the installed capacity of the electromechanical drainage and irrigation station in the western region is positively correlated with the drought disaster rate. The installed capacity of electromechanical drainage and irrigation stations in the eastern region is negatively correlated with the flood disaster rate, but it is positively correlated in the central part of the region.
