Understanding the connotation and principles of ecological compensation in water source reserve areas is the basis and guarantee for establishing and improving the ecological compensation mechanism of water source reserve areas.First,this paper reviews the three stages of ecological compensation research progress.Based on the review,using the theory of externality,the ecological environment system of water source reserve areas is then analyzed.This paper argues that the connotation of ecological compensation in water source reserve areas is a kind of institutional arrangement,which is designed to internalize externalities.Finally,based on the understanding of the connotation of ecological compensation in water source reserve areas,five principles for establishing and improving the ecological compensation mechanism are proposed,including the principle of fairness and justice,the principle of equivalence of equality and responsibility,the principle of flexibility and effectiveness,the principle of "earmark funds,and implementation by law," and the principle of government compensation supplemented with market compensation.

以‘铜陵白姜’(Zingiber officinale ‘Tongling White Ginger’)为试验材料,采用稀释5 000倍液的0.02%二氢卟吩铁(iron chlorine e6, ICe6)可溶粉剂对不同生长时期的‘铜陵白姜’叶面进行喷施,探讨其对姜品质和产量的影响,以期为二氢卟吩铁在生姜上的应用提供科学依据。结果表明, T2处理(三股杈期和第2次小培土时各喷施1次二氢卟吩铁)有利于姜辣素含量增加,比对照(喷施清水, CK)增加74.33%;T1处理(三股杈期喷施1次二氢卟吩铁)和T3处理(三股杈期、第2次小培土和第3次小培土时各喷施1次二氢卟吩铁)的粗纤维含量极显著高于CK, T2处理粗纤维含量极显著低于T1处理和T3处理;3个处理与CK的可溶性总糖含量和含水量均没有显著差异,但粗蛋白含量均极显著低于CK。T2处理和T3处理对‘铜陵白姜’增产作用显著,比CK分别增产22.99%和23.38%。综合考量, T2处理对提高‘铜陵白姜’产量、提升品质效果较好,对种植户的增产增效具有积极作用,应用前景良好。

In view of no generally accepted ecological compensation standards and methods at present,this paper discusses the introduction of the negotiation system to the process of ecological compensation for water source areas.That is,the government in water source areas and the downstream regions of river basins should confirm their respective rights and obligations and then establish their compensation standards through negotiations according to the different purposes of water use.The amount of compensation should be determined in the comprehensive consideration of the quality,quantity and compensation price of water.Through open and fair negotiations,an institutional arrangement will be set up,which can make the water source areas and the downstream regions of river basins fully express their true preferences and their independent choices on the ecological environment.

[目的]在当前化肥施用过量并造成严重面源污染的背景下,需要厘清农户化肥减量行为困境并进行合理的机制设计,实现化肥施用量"负增长"的目标。[方法]文章引入农户从众性行为、政府内源激励、外源激励,构建农户化肥减量行为动力机制理论模型,并通过演化博弈理论和结构方程模型进行理论和实证分析。[结果]减量内生动力,农户从众性行为、减量禀赋间接正向影响减量行为,减量意向具有中介效应;减量外生动力,政府内源激励直接正向影响减量行为,外源激励在减量意向与减量行为之间发挥积极调节作用;仅在政府提供双向激励,策略(双向激励—化肥减量)才能演化为稳定状态。[结论]增强农户减量内生动力,完善基层农业技术推广体系建设和建设标准化果园,充分发挥减量外生动力,加大政府对化肥减量增效技术的宣传教育,尽快落实生态补偿等减量政策。

In this study, we focus on changes in three important components of the hydrological-cycle in the Haihe River basin （HRB） during 1957-2005： precipitation （Prep）, actual evaportranspiration （ETa）, and pan evaporation （PE）-a measure of potential evaporation. The changes in these components have been evaluated in relation to changes in the East Asian summer monsoon. Summer Prep for the whole basin has decreased significantly during 1957-2005. Recent weakening of the convergence of the integrated water vapor flux, in combination with a change from cyclonic-like large-scale circulation conditions to anti-cyclonic-like conditions, led to the decrease in the summer Prep in the HRB. ETa is positively correlated with Prep on the interannual timescale. On longer timescales, however, ETa is less dependent on Prep or the large-scale circulation. We found negative trends in ETa when the ERA40 reanalysis data were used, but positive trends in ETa when the NCEP/NCAR reanalysis data were used. PE declined during the period 1957-2001. The declining of PE could be explained by a combination of declining solar radiation and declining surface wind. However, the declining solar radiation may itself be related to the weakening winds, due to weaker dispersion of pollution. If so, the downward trend of PE may be mainly caused by weakening winds.

厘清流域生态补偿多主体协同程度提升的内在逻辑,对引导整合异质性主体参与流域生态补偿,实现流域生态保护与高质量发展具有重要意义。文中基于山东省大汶河流域的979份社会调查数据,运用层次回归与有调节的中介效应检验方法,实证分析关系质量对流域生态补偿多主体协同程度的影响机理。研究发现:1)关系质量对流域生态补偿多主体协同程度具有显著正向影响。2)主体参与度在关系质量与多主体协同程度间起中介作用,关系质量可通过提高主体参与度间接影响多主体协同程度。3)协同关系促成方式使用度在关系质量与多主体协同程度间同样起中介作用,但高水平关系质量并不会削弱协同关系促成方式的使用程度。此外,从中介效应大小来看,协同关系促成方式使用度>主体参与度,引导型方式使用度>主导型方式使用度。4)政府规制正向调节主体参与度对流域生态补偿多主体协同程度的积极影响。有调节的中介效应检验结果显示,高水平的政府规制下,主体参与度的中介作用较强,关系质量通过主体参与度间接影响多主体协同程度,但在低水平的政府规制下,主体参与度的中介效应并不显著。

研究目的:探讨“多主体协同”对流域生态补偿运行绩效的影响及作用机理,厘清流域生态补偿运行绩效提升的内在逻辑,为构建多主体协同参与的流域生态补偿机制提供参考。研究方法:结构方程模型。研究结果:(1)主体关系、协同态度对流域生态补偿的生态效应、经济效应、社会效应均具有显著正向影响。(2)协同能力对流域生态补偿的生态效应具有显著正向影响,但对经济效应与社会效应则表现出显著的负向影响,侧面反映出现阶段流域生态补偿运行绩效仍不尽人意。(3)主体关系是影响流域生态补偿运行绩效的关键变量,在协同态度、协同能力对运行绩效的影响过程中起中介作用。参与者决策是否与其他利益相关者建立高质量关系主要受沟通、信任及公平的影响。(4)多群组分析结果显示,高质量的主体关系更能提高受益区群体参与流域生态补偿的积极性,进而提升流域生态补偿的社会效应。研究结论:为发挥“多主体协同”在提升流域生态补偿运行绩效方面的积极作用,需重视加强异质性主体对共同参与流域生态补偿的期待与信心,提高各主体生态保护能力、可持续发展能力,优化利益相关者间关系质量。
