【摘要】：糧食的安全存儲一直是糧食行業(yè)的重要環(huán)節(jié)。東北是我國產(chǎn)糧大區(qū),每年由于儲糧方法不當(dāng),造成大量的糧食損失。如果糧食儲藏不考慮氣候因素和外在大氣條件,必然導(dǎo)致糧食發(fā)霉變質(zhì)。因此,要根據(jù)東北不同地區(qū)的自然氣候條件,因地制宜,研究并推廣應(yīng)用合理的儲糧技術(shù),進(jìn)而完善糧食儲藏區(qū)域劃分的方案。結(jié)合目前糧食儲藏技術(shù)的發(fā)展,參照國內(nèi)外糧食儲藏區(qū)域劃分的方法,對糧食儲藏地理區(qū)域劃分指標(biāo)進(jìn)行了重點研究。利用GIS技術(shù)、數(shù)理統(tǒng)計分析等方法,對吉林省和整個東北地區(qū)(包括黑龍江省、吉林省、遼寧省和內(nèi)蒙古東部地區(qū))進(jìn)行了儲糧區(qū)劃研究,并對各儲糧區(qū)域的適宜性進(jìn)行了分析與評價,為吉林省安全儲糧、經(jīng)濟(jì)儲糧提供科學(xué)的參考依據(jù),為儲糧區(qū)劃研究提供有效的方法。本文主要的研究內(nèi)容如下:1、綜合考慮影響糧食儲藏的地理特征與氣候因素,以國家氣象局公開發(fā)表的東北地區(qū)各個氣象觀測站在2001~2012年間所觀測到的每個月份的氣象數(shù)據(jù)(空氣相對濕度、平均溫度、日照時數(shù)、風(fēng)速、降水量)為參考依據(jù),以糧食濕熱平衡模型計算出來的平衡水分為研究對象,對數(shù)據(jù)進(jìn)行整理和修正,以確保研究的數(shù)據(jù)分布均勻,避免數(shù)據(jù)丟失。2、分析氣候條件變化與糧食的安全儲藏之間的密切關(guān)系,探索影響糧食安全儲藏的氣候關(guān)鍵因素。選取合理的糧食儲藏地理區(qū)劃指標(biāo),分析并參考前人的研究成果,結(jié)合東北地區(qū)的實際情況,確定以≥15℃期間的糧食平均平衡水分為糧食儲藏區(qū)域劃分的主要指標(biāo)。首先,將吉林省糧食儲藏區(qū)域劃分為3個區(qū)域,分別是中西部平原區(qū)、中東部半山區(qū)和東部山區(qū)。然后,進(jìn)行了東北地區(qū)的儲糧區(qū)劃研究,將東北地區(qū)劃分為4個大的儲糧區(qū)域。又根據(jù)各區(qū)域的地形和溫度差異情況,選取年平均溫度為區(qū)劃輔助指標(biāo),對其中的三個區(qū)域進(jìn)行了二級劃分。最后,將東北地區(qū)劃分為7個小儲糧區(qū)域,分別是赤峰-通遼丘陵區(qū)、內(nèi)蒙古高原區(qū)、松嫩平原區(qū)、環(huán)渤海灣沿海區(qū)、三江平原區(qū)、小興安嶺山脈區(qū)、長白山脈區(qū)。3、借助地理信息系統(tǒng)的平臺,制作糧食儲藏地理區(qū)劃專題圖。根據(jù)確定的糧食儲藏地理區(qū)劃等級指標(biāo),利用GIS技術(shù),實現(xiàn)對農(nóng)業(yè)氣候資源的可視化和糧食儲藏地理專題區(qū)劃。4、分析了各儲糧區(qū)域各自的氣候特征,為各儲糧區(qū)域采用適宜的糧食儲藏方法提出合理性的建議。
[Abstract]:The safe storage of grain has always been an important link in grain industry. Northeast China is a grain producing region, which causes a large amount of grain loss every year due to improper methods of grain storage. If grain storage does not consider climatic factors and external atmospheric conditions, it will inevitably lead to mildew and deterioration of grain. Therefore, according to the natural climate conditions in different regions of Northeast China, we should study and popularize the reasonable grain storage technology and perfect the plan of dividing the grain storage area according to the local conditions. Combined with the development of grain storage technology at present and referring to the method of dividing grain storage area at home and abroad, the paper makes a key research on the geographical division index of grain storage. Using GIS technology and mathematical statistical analysis methods, the regionalization of grain storage in Jilin Province and the whole Northeast region (including Heilongjiang Province, Jilin Province, Liaoning Province and Eastern Inner Mongolia) was studied. The suitability of each grain storage area is analyzed and evaluated in order to provide a scientific reference for the safe and economical storage of grain in Jilin Province and an effective method for the study of grain storage regionalization. The main research contents of this paper are as follows: 1. The geographical characteristics and climatic factors affecting grain storage are considered comprehensively. Based on the meteorological data (air relative humidity, mean temperature, sunshine hours, wind speed, precipitation) for each month (air relative humidity, average temperature, sunshine hours, wind speed, precipitation), which were observed by various meteorological observation stations in the Northeast region during the period of 2001 to 2012, which were publicly published by the National Meteorological Administration, The equilibrium water calculated from the model of moisture and heat balance of grain is divided into study objects, and the data are collated and revised to ensure the uniform distribution of the data. To avoid data loss. 2, to analyze the close relationship between climate change and grain security storage, and to explore the key climatic factors that affect food security storage. Selecting reasonable grain storage geographical regionalization indexes, analyzing and referring to the previous research results, combining with the actual situation in Northeast China, it is determined that the main indexes of grain storage area division can be divided into grain average equilibrium water in the period of 鈮，
