Planting Structure Adjustment and Layout Optimization of Feed Grain and Food Grain in China Based on Productive Potentials

Increasing feed grain supply, particularly domestic is intended to guarantee security and, as a result, food security. Based on the Global Agro-Ecological Zones (GAEZ) model, potential yield and actual of in China were estimated. According theory factor endowment, development coefficient efficiency advantage index then constructed determine whether current spatial layout reasonable how it could be adjusted. The results showed that: (1) There was an imbalance crops production: loss high-potential regions excessive low-potential regions. imbalances lead mismatch between production resource endowment which causes productivity losses ecological risks. (2) considerable for increasing Northeast Plain, Loess Plateau northern arid semiarid region. soybean can increased by about 25%, maize even more. (3) should planted with sufficient but insufficient yield; 26.42% China’s soybeans 34.74% its these (4) Some 16.69% 15.65% wheat rice planting areas adjusted soybeans, respectively; 20.76% 21.04% maize, respectively. Through agricultural technology research development, infrastructure support, comprehensive planning design policy design, potentials realized. This will redress wherein surplus shortage coexist.
