    摘要:

    從水土資源協同投入和“經濟-社會-生態(tài)”效益產出的全局角度分析宏觀區(qū)域的農業(yè)水土資源利用效率,,對于農業(yè)生產可持續(xù)性具有重要價值。本文結合廣義水資源概念及農業(yè)生產中的“多投入-多產出”特征,,闡明了農業(yè)水土資源利用效率的內涵,,利用數據包絡分析法構建了超效率-基于松弛變量(Super-SBM)模型和超效率-考慮非期望產出-基于松弛變量(Super-Undesirable-SBM)模型用于測算生產配置效率概念的農業(yè)水土資源利用效率,并以山東省引黃灌溉區(qū)為例,,測算了研究區(qū)51個縣域的不考慮生態(tài)效益的農業(yè)水土資源利用效率(WLUE),、考慮生態(tài)效益的農業(yè)水土資源利用效率(WLUEE)、水資源利用效率損失(WUEL)和耕地資源利用效率損失(LUEL)。結果表明:所有縣域中,,只有東明縣和桓臺縣WLUE和WLUEE均大于1,,實現了DEA有效,河口區(qū)的WLUE最小,,歷城區(qū)的WLUEE最小,。各縣域分為綠色高效型、普通高效型,、綠色低效型和普通低效型4種類型,,且綠色高效型和普通高效型縣域水資源利用水平更高,綠色低效型和普通低效型縣域耕地利用水平更高,。提出了不同類型縣域農業(yè)水土資源利用效率的針對性改善措施,,為農業(yè)水土資源利用效率研究提供新的視角,研究成果有利于促進研究區(qū)農業(yè)生產的可持續(xù)發(fā)展,。

    Abstract:

    It is important to analyze the efficiency of agricultural water and land resources utilization in macro-regions from the perspective of synergistic inputs and “economic-social-ecological” benefits for the sustainability of agricultural production. The connotation of agricultural water and land resources use efficiency was clarified by combining the broad concept of water resources and the characteristics of “multiple inputs-multiple outputs” in agricultural production, the super slacks based measure (Super-SBM) model and super undesirable slacks based measure (Super-Undesirable-SBM) model were constructed by using data envelopment analysis to measure the production allocation efficiency. The Super-SBM model and Super-Undesirable-SBM model were used to measure the efficiency of agricultural water and land resources utilization of the concept. Agricultural water and land resources utilization efficiency without considering ecological benefits (WLUE), agricultural water and land resources utilization efficiency with considering ecological benefits (WLUEE), water resource utilization efficiency loss (WUEL) and arable land resource utilization efficiency loss (LUEL) were measured for 51 counties in the study area, taking the Shandong Yellow Diversion Irrigation District as an example. By comparing and analyzing the WLUE and WLUEE measurement results, WUEL and LUEL decomposition results, the characteristics of agricultural water and soil resource utilization and the size difference of the two resource utilization efficiency losses in each county of the study area were revealed, and the counties of the study area were classified into four types: green and efficient production type, ordinary efficient production type, green and inefficient production type and ordinary inefficient production type. The targeted improvement measures for agricultural soil and water resource use efficiency in each county and a perspective for the study of agricultural soil and water resource utilization efficiency were proposed. The research results were conducive to promoting the sustainable development of agricultural production in the study area.
