文章摘要:為了探索以農(nóng)業(yè)為主的少數(shù)民族地區(qū)農(nóng)業(yè)可持續(xù)發(fā)展能力及未來(lái)趨勢(shì)的變化規(guī)律,探討該地區(qū)農(nóng)業(yè)可持續(xù)發(fā)展制約因素,以貴州省黔東南苗族侗族自治州為研究區(qū)域,結(jié)合黔東南州的農(nóng)業(yè)、社會(huì)和經(jīng)濟(jì)發(fā)展特點(diǎn),構(gòu)建了該地區(qū)農(nóng)業(yè)可持續(xù)發(fā)展評(píng)價(jià)指標(biāo)體系,并運(yùn)用主成分分析方法(PCA)對(duì)該地區(qū)農(nóng)業(yè)可持續(xù)發(fā)展?fàn)顟B(tài)進(jìn)行定量分析,在此基礎(chǔ)上應(yīng)用灰色GM(1,,1)模型對(duì)該地區(qū)農(nóng)業(yè)可持續(xù)發(fā)展能力進(jìn)行趨勢(shì)預(yù)測(cè)。結(jié)果表明:該地區(qū)2000-2009年農(nóng)業(yè)經(jīng)濟(jì)子系統(tǒng)、農(nóng)業(yè)生產(chǎn)子系統(tǒng)、農(nóng)業(yè)社會(huì)子系統(tǒng)與農(nóng)業(yè)可持續(xù)發(fā)展總體水平都在持續(xù)增長(zhǎng),而農(nóng)業(yè)資源與環(huán)境能力不斷下降,2003年開始出現(xiàn)低于平均水平的情況。隨著農(nóng)業(yè)經(jīng)濟(jì)、生產(chǎn)與社會(huì)發(fā)展,農(nóng)業(yè)資源與環(huán)境的壓力目益加大,今后的發(fā)展將可能面臨嚴(yán)重的資源短缺和環(huán)境退化的制約。模型趨勢(shì)預(yù)測(cè)計(jì)算結(jié)果經(jīng)殘差檢驗(yàn)和后驗(yàn)差檢驗(yàn)表明,其平均相對(duì)誤差為0.062,后驗(yàn)比C=0.2169,誤差概率P=1,表現(xiàn)出高的預(yù)測(cè)精度。預(yù)測(cè)結(jié)果顯示,2010-2020年黔東南州的農(nóng)業(yè)可持續(xù)綜合發(fā)展能力仍繼續(xù)上升,但只遞增了5.07倍,這表明該地區(qū)農(nóng)業(yè)可持續(xù)能力發(fā)展還存在諸多限制因素。以期對(duì)黔東南的農(nóng)業(yè)可持續(xù)發(fā)展提供科學(xué)依據(jù),為政府農(nóng)業(yè)決策者理論支持。
Abstr:In order to explore sustainable agricultural development capabilities and future trends rules in ethnic minority areas which was agriculture-based regions, taking Qiandongnan Miao and Dong Autonomous Prefecture (Qiandongnan) for example, sustainable development index system of agriculture was built by fully integrated characteristics of the agricultural and economic development in Qiandongnan Miao and Dong Autonomous Prefecture (Qiandongnan). The principal component analysis (PCA) method was used to quantitatively analyze the status of sustainable development of agriculture, and then the GM (1,1) model was used to predict the trend of agricultural sustainable development in Qiandongnan. The results showed that, the development trends of agricultural economic subsystem, agricultural production subsystem and agricultural society subsystem were the similar with the total agricultural sustainable development, increased year by year between 2000--2009, but the agricultural resources and environment subsystem declined and sustainability was below the average level since 2003. It mean that with the development of the agricultural economy,production and society, the pressure on the agricultural resources and environment was growing, so further development would likely faced the serious shortages of resources and constraints of environmental degradation. The predicted results passed the posterior-variance-test and residual analysis by gray modeling method and showed high precision, these results includes the average relative error of calculation is 0.062, C= 0.2169, P=1. The prediction revealed that, keep comprehensive capacity of agriculture on rising, but only increased 5.07 times for the next 11 years. It showed that, a certain number of
