Compared with the three major grain crops , potato planting area can be further increased by using the winter fallow fields and its yield can be further increased as well 可利用冬閑田進(jìn)一步擴(kuò)大馬鈴薯種植面積,與三大糧食作物相比,其單產(chǎn)還有較大的增加潛力。
This paper presents a means of evaluating and analysing agricultural climate resource and weather disaster in the county wulancabu and jiangsu province based on gis technique and climate resource information . the indicators of climate and risk which includes fail and lost risks for potato growing in the county wulancabu , located in the middle of inner - mongolia area , are given according to the spatial statistic results of multi - natural resources in the county 為了充分而合理的利用自然氣候資源,本文依托地理信息系統(tǒng)( gis ) ,以該地區(qū)為例,對(duì)馬鈴薯做了多項(xiàng)自然資源空間統(tǒng)計(jì)分析,確定了馬鈴薯種植的氣候區(qū)劃指標(biāo),并從馬鈴薯歷年糧食產(chǎn)量單產(chǎn)偏離趨勢(shì)產(chǎn)量的波動(dòng)副值百分率著手,定義了反映烏盟馬鈴薯產(chǎn)量風(fēng)險(xiǎn)水平的風(fēng)險(xiǎn)指標(biāo)。
