摘 要:為了協(xié)調(diào)黃河流域水資源與經(jīng)濟(jì)社會(huì)發(fā)展之間的關(guān)系,基于2008—2022年山東省黃河流域用水現(xiàn)狀數(shù)據(jù),采用信息熵和均衡度、洛倫茨曲線和基尼系數(shù)等,分析山東省黃河流域用水結(jié)構(gòu)演變特征及空間分布規(guī)律。結(jié)果表明:山東省黃河流域農(nóng)業(yè)用水不再具備單一的絕對(duì)優(yōu)勢(shì),水資源分配正向多目標(biāo)轉(zhuǎn)化;信息熵和均衡度呈同步上升趨勢(shì),表明各類用水量的分布向均勻性發(fā)展;2008—2022年山東省黃河流域農(nóng)業(yè)用水的空間均衡度明顯下降,工業(yè)用水的空間均衡度略微上升,生活用水的空間均衡狀態(tài)未出現(xiàn)較大變化,生態(tài)用水的空間均衡度明顯提升;2008—2022年山東省黃河流域農(nóng)業(yè)用水的空間分布由明顯均衡狀態(tài)變?yōu)楸容^均衡狀態(tài),工業(yè)和生活用水的空間分布一直為比較均衡狀態(tài),生態(tài)用水的空間分布由均衡較差狀態(tài)變?yōu)楸容^均衡狀態(tài);德州的農(nóng)業(yè)用水量占比最高,淄博的工業(yè)用水量占比明顯超過其他區(qū)域,濟(jì)南的生活用水量占比最高且緩慢上升,2018年濟(jì)南生態(tài)用水量占比最高,德州生態(tài)用水量占比最低。

水資源是人們賴以生存的基本自然資源,也是維持生態(tài)系統(tǒng)的決定性要素[1]。我國人均水資源量嚴(yán)重不足,僅為世界平均水平的1/4,同時(shí)面臨水資源時(shí)空分布不均衡、利用效率低等問題[2],水資源短缺嚴(yán)重影響我國經(jīng)濟(jì)社會(huì)可持續(xù)發(fā)展。……
