摘要
运用秸秆草谷比测算2011—2020年黑龙江省玉米秸秆资源量,探析黑龙江省玉米秸秆资源量时间变化趋势,进一步运用ArcGIS软件和九宫矩阵图,直观反映玉米秸秆空间分布区域特征和单产层级。结果表明:(1)2011—2020年黑龙江省玉米播种面积、玉米产量整体呈先上升后下降的态势。(2)黑龙江省玉米秸秆资源量主要集中在西南地区的哈尔滨、绥化、齐齐哈尔3市,单产区域分布呈现出“西南—东北”带状分布特征。(3)通过九宫矩阵图可将黑龙江省玉米秸秆生产划分为丰裕、一般、贫乏三大类型区,各地区应结合当地资源状况合理布局秸秆资源化利用模式。
Taking the advantage of the grain-straw ratio of straw,this paper estimated the maize straw resources in Heilongjiang Province from 2011 to 2020.This paper explored the temporal variation trend of maize straw resources in Heilongjiang Province,and reflected the regional characteristics of the spatial distribution of maize straws and the level of yield per unit area by further using ArcGIS software and the 9-room diagram matrix.The results showed that:①The sowing area of maize and the output of maize in Heilongjiang Province ascended and then fell from the year 2011 to the year 2020.②The resources of maize straw in Heilongjiang Province are mainly concentrated in three cities,namely Harbin,Suihua,and Qiqihar in the southwest of China,and the areal distribution of unit yield showed the zonal distribution characteristics of“Southwest-Northeast”.③The production of maize straw in Heilongjiang Province has been divided into the three types of areas as follows,that is,abundant type,average type,and poor type through the 9-room diagram matrix,so each area should properly arrange the straw resource utilization model in accordance with the local resource situations.
