Assessment of grain production potential in Songnen Plain and relevant suggestions
摘要
Abstract
Songnen plain production potential and contributions of its major impact factors were assessed by using analytic hierarchy process (AHP) method derived from Accumulation Factor Sequence Evaluating weight method.Recommendations and some suggestions were proposed based on the study results and the current situation of Songnen plain grain production.The study results showed that Harbin,Suihua and Changchun had the highest grain production potential,and Heihe City had the smallest one.Water and soil resource and climatic condition were major limit factors causing the difference of production potential,and contribution weight of both of them were 0.28.The second factor causing production potential difference was science and technology investment,and its contribution weight was 0.25.In Songnen Plain,black soil ratio was the largest factor determining the food production potential ; its contribution weight was 0.22.Average temperature and fertilizer use were also the important factors for food production potential,and their contribution weights were 0.13 and 0.10.In conclusion,to improve food production,it is very important to enhance the protection of black soil and strengthen the construction of farmland water conservancy infrastructure,to increase investment and promote application of agricultural science and technology,and to expand the planting area of high-yield crop or species that adapted well to the climate warming.关键词
