摘要:
区域的粮食生产与生态价值存在相互促进和制约的特殊关系。本研究基于生态系统服务价值ESV范式构建了生态农业协调度EAH模型,进而对中国粮食主产区(河北、内蒙古辽宁、吉林、黑龙江、江苏、安徽、江西、山东、河南、湖北、湖南、四川)粮食生产与生态环境的协调性进行实证研究和预警预测。研究发现,2017年中国粮食主产区总体协调度为1.27,处于中度协调水平,粮食主产区农业-生态协调性较差,错位现象较为严重。从动态属性看,研究期间农业-生态协调性形成了以2013年为拐点的倒U型趋势,当前粮食生产与生态服务价值协调性逐年下降,灰色系统GM(1,1)预测显示,相比2011-2017年,2019-2025年农业-生态协调性呈逐渐弱化趋势。从空间属性看,粮食生产与生态服务价值存在较为突出的地理空间分异和不协调现象。
Abstract:
There is a special relationship between regional food production and ecological value. Based on the paradigm of ecosystem service value (ESV), an ecological agriculture coordination degree model was constructed, and then the coordination between food production and ecological environment in major grain-producing areas(Hebei, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Jiangsu, Anhui, Jiangxi, Shandong, Henan, Hubei, Hunan, Sichuan) was studied and predicted. The results showed that the overall coordination degree of China′s major grain-producing areas was 1.27 in 2017, which was at the level of moderate coordination. The agro-ecdogical coordination in major grain-producing areas was poor, and the dislocation was serious. From the perspective of dynamic attributes, the agro-ecological coordination during the study period formed an inverted U-shaped trend with 2013 as the inflection point. The coordination between current food production and ecological service value was declining year by year. The gray system GM(1,1) prediction results showed that the coordination in 2019-2025 was gradually weakening compared with that in 2011-2017. From the perspective of spatial attributes, the value of food production and ecological service was not coordinated in geographic space.
