| The fast-growing and high-yielding timber plantation base construction project initiated in 2002, and it’s the sixth largest forest project in China. Did the project have influence to the grain production in the past ten years? And how much the influence is?Based on this problem, the study select Hebei province as the research area, which is around the Beijing-Tianjin, and the geographical position is particularly important. It analyzes Hebei’s fast-growing woods planting area, grain sown area and yield from land using angle.Research shows that fast-growing woods planting’s time and space difference is very wide in Hebei and each city, but its influence is very small for the grain sown area, and has no effect on food production. Because Fast-growing woods can improve ecological environment and bring huge economic benefits, it can continue to be planted in Hebei’s suitable area in the future. The fast-growing woods planting should occupy less cultivated-land as far as possible, and reduce the influence to grain production. |
