| Abstract: | Based on geographical information system(GIS) technology,this research attempts to study the potential productivity of maize in western mountainous of Henan province by applying theoretical models(Agro-ecological Zone,AEZ),and analyzes the differences of the productive potential resources utilization efficiency with actual production data.The results show that the potential photosynthetic and photo-temperature productivity tends to increasing from the middle to surrounding;the potential climate and nature productivity displays high in south and low in north;respectively,the average of photosynthetic,photo-temperature,climate and nature productive potential resources utilization efficiency at county level is 6.13 %,31.72 %,39.03 % and 56.11 %,which shows that the present maize productivity has more than 16 double,3 double,2.5 double and 2/5 increase space according to the potential photosynthetic,photo-temperature,climate and nature productivity. |
