- Abstract:
- Regional grain supply balance is an important indicator for national minority food security. Based on GIS techniques and spatial statistics analysis, regional pattern changes characters and its reasons of grain production from 1985 to 2006 in Ningxia Hui Autonomous Region were analyzed. The results showed that the general tendency of grain production in Ningxia had increased, and per capital grain possession had increased gradually, grain-output region and main grain-output region distributed along the yellow river in spatial. Region difference of grain production decreased. The study also found that the existence of spatial differentiation of grain production with population distribution decreased gradually. Irrigation area was the important region of grain production in Ningxia, but the area extent was continuous to the arid region in middle Ningxia. The main forces of regional changes of capital grain possession were some projects implementing, such as water resources project, returning cultivated land to forest, eco-immigration and so on.
