【摘要】：寧夏是中國(guó)釀酒葡萄生產(chǎn)最佳生態(tài)區(qū)之一。但由于寧夏的地形及特殊的地理位置,再加上冬季寒潮影響,使葡萄安全越冬受到了一定的威脅,通過(guò)研究建立釀酒葡萄綜合凍害指數(shù)以及對(duì)寧夏釀酒葡萄凍害進(jìn)行風(fēng)險(xiǎn)區(qū)劃對(duì)該區(qū)域釀酒葡萄的種植與管理有很強(qiáng)的現(xiàn)實(shí)意義,并為促進(jìn)寧夏釀酒葡萄的發(fā)展提供理論基礎(chǔ)與指導(dǎo)。本文選取冬季極端最低氣溫、降溫持續(xù)的時(shí)間、平均最低氣溫等氣象因子作為釀酒葡萄越冬期凍害氣象指標(biāo)。并運(yùn)用主分量分析方法計(jì)算得到釀酒葡萄綜合凍害指數(shù),然后采用線性回歸、Mann-Kendall檢驗(yàn)以及Morlet小波分析方法對(duì)綜合凍害指標(biāo)進(jìn)行分析,最后依據(jù)自然災(zāi)害風(fēng)險(xiǎn)理論,從孕災(zāi)環(huán)境敏感性、致災(zāi)因子危險(xiǎn)性、承災(zāi)體脆弱性及防災(zāi)減災(zāi)能力四個(gè)方面進(jìn)行分析,最后對(duì)寧夏釀酒葡萄越冬期凍害風(fēng)險(xiǎn)開(kāi)展評(píng)估和區(qū)劃,并結(jié)合2015-2016年度在寧夏永寧縣閩寧鎮(zhèn)玉泉營(yíng)葡萄基地和原隆村開(kāi)展的釀酒葡萄凍害實(shí)驗(yàn)結(jié)果加以討論,得到如下結(jié)論:1.凍害指數(shù)越低,釀酒葡萄發(fā)生凍害越嚴(yán)重。分析確定了 0為寧夏釀酒葡萄凍害的臨界指標(biāo)。近55a以來(lái)葡萄凍害指數(shù)有一定上升趨勢(shì),綜合凍害指數(shù)年代際變化以25～30a的周期信號(hào)明顯,年代變化上在5a和10-15a的周期信號(hào)上也較明顯。2.永寧縣凍害實(shí)驗(yàn)地點(diǎn)的氣溫與地溫之間存在顯著性水平的相關(guān)。試驗(yàn)結(jié)果表明,為確保寧夏釀酒葡萄安全越冬,必須要使下架葡萄的覆土深度大于40cm,使根系區(qū)域的地溫大于-5℃。3.寧夏的西吉縣中部、鹽池縣、陶樂(lè)縣、固原市原州區(qū)、惠農(nóng)縣和平羅縣的部分地區(qū)屬于綜合凍害高風(fēng)險(xiǎn)以及次高風(fēng)險(xiǎn)區(qū)域;寧夏北部地區(qū)的永寧縣、銀川市郊區(qū)、賀蘭縣、靈武市,寧夏中部地區(qū)的中衛(wèi)和同心的東部,寧夏南部地區(qū)的彭陽(yáng)和涇源部分地區(qū)處于綜合凍害中級(jí)風(fēng)險(xiǎn)區(qū);寧夏其余地區(qū)處于低和次低級(jí)別的風(fēng)險(xiǎn)區(qū),并主要集中在寧夏中部地區(qū)。評(píng)估與區(qū)劃結(jié)果表明:寧夏釀酒葡萄越冬期凍害風(fēng)險(xiǎn)評(píng)估模型比較客觀,較全面地反映出該區(qū)域的凍害風(fēng)險(xiǎn)水平。
[Abstract]:Ningxia is one of the best wine grape production China ecological zone. But due to the topography of Ningxia and the special geographical location, coupled with the impact of the cold winter, the winter grape security threat, and pass the research to establish comprehensive freezing index and wine grape of Ningxia wine grape frost risk division has a strong practical significance and cultivation the management of the regional wine grape, and provide a theoretical basis and guidance for promoting the development of Ningxia wine grape. The extreme winter minimum temperature, cooling duration, average minimum temperature of gas like factor as freezing weather index during winter grapes. And using the calculated index of grape comprehensive freezing method of principal component analysis then the linear regression method, carries on the analysis to the comprehensive disaster indices of Mann-Kendall test and Morlet wavelet analysis, finally, according to the natural From the theory of disaster risk, disaster environmental sensitivity, hazard risk, vulnerability and disaster prevention and mitigation capacity of four aspects of analysis, the final of the Ningxia wine grape winter freezing disaster risk assessment and zoning and carry out, with 2015-2016 year in Ningxia Yongning County of Fujian Ningzhen Yuquanying grape wine grape base and long the experimental results of the village to carry out damage to be discussed, the conclusions are as follows: 1. frost damage index is low, the wine grape freezing injury more serious. The analysis identified 0 Ningxia wine grape freezing critical index. Since the last 55A grape freezing index has a certain upward trend, comprehensive freezing index and interdecadal variation in 25 ~ 30A obvious periodic signal in the change, between air temperature and ground temperature in the periodic signal 5A and 10-15A have obvious.2. Yongning County freezing study sites level exists significant correlation. The test results table In Ming Dynasty, in order to ensure the safety of winter Ningxia wine grape, must make the Overburden Depth under the frame of grapes is greater than 40cm, the temperature is greater than the central root zone, Xiji County -5 C.3. Ningxia Yanchi County, Taole County, Yuanzhou District of Guyuan City, part of Huinong County peace Luo County belongs to the high risk and comprehensive damage high risk area; Ningxia northern suburb of Yinchuan City, Yongning County, Helan County, Lingwu City, Ningxia central defender and concentric Eastern, southern Ningxia and Pengyang Jingyuan in some areas in the comprehensive freezing medium risk area; the rest of Ningxia is low and low risk level regions, and mainly concentrated in the central area of Ningxia. The results show that the evaluation and regionalization of Ningxia wine grape winter frost risk assessment model objectively, comprehensively reflects the level of the region. The risk of freezing injury
