| The mountainous area of Hebei Province is the agricultural and sideline product supply base in the Beijing-Tianjin-Hebei region.It is the ecological barrier of the North China region.It is a solid backing for the construction of the Xiong'an New District.The development of the mountainous economy is an important part of the economic development of Hebei Province.As a leading industry in the mountainous economy,the planting industry plays an important role in improving the mountain ecological environment,increasing farmers' income and improving people's living standards.This paper takes the mountainous planting industry in Hebei Province as the research object,and establishes the current production status of crops(wheat,corn,beans,oilseeds,rice,vegetables)in mountainous areas(Taihang Mountain,Yanshan and Bashang)by establishing the main crop database in mountainous areas of Hebei Province;Through the comprehensive comparative advantage index of the main crops in mountainous counties(cities,districts),the comprehensive production comparative advantages and the factors affecting the formation of the main crops in the mountainous areas were comprehensively analyzed.The research results are as follows:(1)Using the combination of computer technology and professional knowledge,the main crop database of mountainous areas in Hebei Province was established,and the professional maps were generated through the database visualization link system.The spatial and temporal distribution of main crop production in mountainous areas of Hebei Province in the past decade was analyzed.The results showed that: The change of wheat planting area in 2008-2012 was relatively small,basically in a stable state.The planting area increased from 2012 to 2014 year by year,and the planting area dropped after 2014.The area planted with corn in the mountainous areas was in a slow increase from 2008 to 2014,with a small increase.The area increased in 2015,but fell back to the level of 2014 in 2016.The planting area of soybeans,oilseeds and rice in mountain areas continued to decline between 2008 and 2016,with a decline of 34.93%,4.83% and 17.75% respectively.During the period,the area planted with vegetables increased the most,increasing by 12.07%.(2)The comprehensive advantage index method was used to analyze the comprehensive production comparative advantages of six crops in mountainous areas of Hebei Province.The results showed that compared with the whole province,the comparative advantage index of main crop production in mountainous areas was different.The scale advantage index of main crops in Taihang mountain area was ranked as corn>soybean>oil>wheat>1>vegetable>rice,the efficiency advantage index ranked as 1>corn>soy>wheat>vegetable>oil>rice,comprehensive comparative advantage index ranked as corn>1>soy>wheat>oil>vegetable > rice,corn in the Taihang Mountains has a strong comprehensive comparative advantage,and the rice performance is a significant disadvantage;the comparative advantage index of the main crops in the Yanshan Mountains is ranked as soybean > rice > corn > vegetables > oil > 1 > wheat,and the efficiency advantage index is ranked as corn>soybean>1>vegetable>oil>rice>wheat,the comprehensive advantage index is ranked as corn>soy>vegetable>1>rice>oil>wheat,and corn,soybean and vegetable in Yanshan mountain area show strong comprehensive comparative advantage;The comparative advantage index of major crops in Bashang area is ranked as oil>vegetable>1>corn>wheat>soy>rice,and the efficiency advantage index is ranked as Vegetables>1>rice>soybean>corn>oil>wheat,the comprehensive advantage index is ranked as vegetables>1>oil>soap>corn>rice>wheat,vegetables in the Bashang area have a comparative advantage in scale,efficiency advantage and comprehensive comparative advantages,corn,soybeans,rice,wheat,the performance of the scale is relatively inferior,the efficiency is relatively inferior and comprehensive comparative disadvantage.(3)The regional comparative advantage index model method was used to analyze the regional comparative advantages of the main crops in the counties(cities,districts)of the mountainous areas.The results showed that there were differences in the comprehensive comparative advantages of the main crop production in the mountainous counties(cities,districts)compared with the mountainous areas.In terms of wheat production,there are 13 counties(cities,districts)in the Taihang Mountains with comprehensive comparative advantages.The comprehensive comparative advantages of the counties(cities,districts)in the Yanshan Mountain Area and the Bashang Area are at a disadvantage.In terms of corn production,there are 18 and 25 areas with comprehensive advantages in the Taihang Mountains and Yanshan Mountains,and the Bashang area does not have comprehensive comparative advantages.In terms of soybean production,there are 14 counties(cities,districts)in the Taihang Mountains with comprehensive comparative advantages;26 counties(cities,districts)in the Yanshan Mountains with comprehensive comparative advantages;and comprehensive comparison of soybean production in the Bashang area Both are at a disadvantage.In terms of oil production,there are 9 counties in Taihang Mountain area with comprehensive comparative advantages;10 counties(cities,districts)in Yanshan Mountain have comprehensive comparative advantages;Shangyi County is the only comprehensive comparative advantage of oil production in Bashang area.In terms of rice production,Shexian County is the most comprehensive comparative advantage area in Taihang Mountain Area;in Yanshan Mountain Area,Longhua County has the most significant performance in comprehensive comparative advantage.In terms of vegetable production,there are 3 counties(cities,districts)in areas with obvious comprehensive comparative advantages;the Shanhaiguan District in Yanshan Mountain Area is the most significant area with comprehensive advantages.Shangyi County,the most significant area with comprehensive comparative advantage in the Bashang area.According to the comparative advantage results of the main crops,the distribution map of the main crops in the mountainous areas of Hebei Province was produced and imported into the database for convenient and quick inquiry.(4)Through econometric analysis,the factors affecting the comparative advantage of major crop areas in mountainous areas were studied.The results showed that the planting area,irrigated area,agricultural machinery power,fertilizer input increased and grain yield showed a positive correlation,and the increase of disaster area and crop yield were negative.relationship.In summary,through the visualization link generation system in the database,the visualization of thematic maps is generated,and the temporal and spatial distribution of the main crops in the mountainous areas of Hebei Province is clarified.The comprehensive production index comparative analysis of the six crops in the mountainous areas and the planting Advantage County,the regional comparison results are imported into the database through ARCGIS to generate the theme map.And through the econometric analysis of the factors affecting the comparative advantage of crop areas.This is used as the basis for optimizing the layout of mountain crops. |
