摘要：利用Arc GIS软件和趋势倾斜率,对2005—2015年我国农业产值结构时空变化特征进行分析。结果表明:11年间,我国大部分地区种植业产值比例和渔业产值比例呈上升趋势,牧业产值比例呈下降趋势。我国北方大部分地区林业产值比例呈下降趋势,南方大部分地区呈上升趋势。种植业产值比例变化与耕地灌溉面积、农业机械总动力、化肥使用量相关性较强。林业产值比例变化与造林面积、森林蓄积量、森林覆盖率相关性较强。牧业产值比例变化与牧草地面积、种草面积相关性较强。渔业产值比例变化与近海和海岸面积、河流和湖泊面积相关性较强。
Using the ArcGIS software and trend slope,the spatial and temporal variations of agricultural production value structure in China from2005to2015were analyzed.The results showed that the proportion of both plantation industry value and fishery production values showed an increasing trend in most regions of China,while the proportion of animal husbandry production value showed a decreasing trend.The proportion of forestry production value in most regions of Northern China had been declining,while an increasing trend for forestry production was found in most regions of Southern China.Changes in the proportion of plantation production values were highly correlated with irrigation area,total agricultural machinery power and chemical fertilizer usage.Changes in the proportion of forestry production value were correlated with forest area,forest volume and forest coverage rate.There was a strong correlation between the proportion of animal husbandry production value change and the forage and grass planting areas as well as between the proportion of fishery production value change and offshore and coastal areas and river and lake areas.
