摘要
本研究应用层次分析法从经济效益、技术可推广性和环境效益3个维度对丹江口水源涵养区示范的13项技术是否符合绿色高效农业特征进行评价,为可复制、可推广的技术在该区域及类似区域应用提供技术支持。通过收集研发专家的技术试验和示范数据以及地方专家对评价指标重要性的判断和各技术指标估值调查问卷数据,利用Yaahp软件对收集问卷的重要性判断表的准则层、子准则层和指标层的各指标进行权重值(q)i计算。依照生态补偿测算相关方法对量化指标的技术示范测算值进行估算,然后结合各技术量化指标取值范围均值计算单项量化指标评分分值,其他定性指标评分分值取调查问卷均值。根据各单项指标评分分值与权重,计算各技术的评价总分。评价结果表明:经济效益、技术可推广性和环境效益3个维度指标的权重设置符合绿色高效农业技术评价体系的属性和特征,依据技术实施效果得到的综合评分可用于评价丹江口水源涵养区示范的农业技术。从综合评价得分来看,丹江口水源涵养区示范的13项技术取得较好效果,其中3项技术大于8分,8项技术大于7分,2项技术大于6分,尤其是养殖废弃物农田安全高效消纳、低氮磷排放环保饲料配制、魔芋病害防控3项技术综合评价得分大于8分,综合评价为优秀。总体上综合得分合格率为100%,良好率为61.54%,优秀率为23.08%。研究表明,丹江口水源涵养区示范的13项技术为绿色高效农业技术,适于在该区域及类似区域推广应用。
The effect of implementing thirteen green and efficient agro-technologies in the Danjiangkou water conservation area were evaluated using the three dimensional indices of economic benefit,technology extensibility,and environmental benefit via the analytic hierarchy process to provide technical support for the application of these technologies.We collected tested and demonstrated data from technology R&D experts to use as the basis for local experts to fill in the quantitative and qualitative index values in the questionnaire and estimate the values of quantitative indices for the demonstrated agro-technologies.We obtained local expert judgements of the importance of and values for the agro-technical evaluation indices.Yaahp software was used to calculate the weight value(q)i of each index in the criterion,index and sub-index layers according to the importance judgment.The importance judgment questionnaires were only accepted one if the questionnaires′data were the same and were eliminated if the data failed to pass the consistency test.Then,the mean value Qi of each index weight of the effective questionnaires was calculated.The estimated values of the technologies were calculated,based on ecological compensation calculation methods,for seven quantified indicators including construction cost,operation cost,extension cost,environmental costs,technology benefit,resource savings,and supply function.The evaluation score for each indicator was then calculated based on the range of mean values for each technical indicator on the questionnaires.The evaluation scores of qualitative indices such as innovation and advanced nature,stability,maturity,research foundation,intellectual property,potential risk,and support and adjustment function were calculated based on the range of mean values for each technical indicator from the questionnaires.Finally,the total evaluation score for each technology was calculated using the evaluation score and weight of each index.The evaluation system for the three dimensional indices of economic benefit,technology extensibility,and environmental benefit was in line with the system of evaluating green and efficient agro-technology,and could thus be used to evaluate the effect of implementing the latter in the Danjiangkou water conservation area based on the comprehensive score.From the comprehensive evaluation scores,the 13 agro-technologies demonstrated in the Danjiangkou water conservation area achieved good results,and of them three technologies had scores of eight or more points,eight had scores from seven or more to less eight points,and two had scores from six or more to less seven points.The comprehensive evaluation score of three technologies-breeding waste consumed safely and efficiently on farmland,feed formulated with low nitrogen and phosphorus emissions,and environmentally friendly and konjac disease prevention and control scored more than eight points and had an excellent comprehensive evaluation.Generally,the qualified rate of the comprehensive score was 100%,the good rate was greater than 61.54%,and the excellent rate was greater than 23.08%.The 13 demonstrated agro-technologies were green and efficient,meaning they are suitable for the Danjiangkou water conservation area and similar regions.
