Abstract:

Under the background of the agricultural supply-side structural reform and rural revitalization, it is critical to raise farmers' income, realize sustainable agricultural development and guarantee food security by developing multiple agriculture functions in various regions and coordinating the development of regions with different agricultural functional characteristics. The spatio-temporal differentiation of agricultural multifunctions results from the comprehensive effects of the agricultural resource endowments and the socio-economic development level and stages. This paper constructs an evaluation index system of agricultural multifunctions. Taking Shandong province as an example, this paper analyzes the spatio-temporal evolution characteristics and driving mechanisms of agricultural multifunctions at county level from 2004 to 2017 by using spatial mismatch, regression analysis and so on. The results are shown as follows: The spatio-temporal evolution characteristics of agricultural functions in the province were significantly different during 2004-2017. Among them, the agricultural products supplying function showed a growth trend of increasing first and decreasing afterwards, and its high-value areas were mainly distributed in the "half-ring" area surrounding the south-central mountainous area of Shandong province; the economic development function showed a growth trend of decreasing first and increasing afterwards, and its high-value areas were transformed from traditional agricultural areas with high proportion of agriculture to modern agricultural areas with high agricultural output value and distinctive agricultural areas which have high-value agricultural products or prosperous correlative industries such as agricultural tourism; the social security function showed a downward trend, and its high-value areas were concentrated in the grain producing areas with large farmland area per labor and the mountainous-hilly areas with distinctive agriculture; the ecological service function showed a downward trend of decreasing first and increasing afterwards, and its high-value areas were mainly distributed in mountainous-hilly areas with good ecological basement. The impact of factors on different elements of the same function differed in direction and extent, which resulted in changes of agricultural functional structure. Finally, based on the functional perspective, this paper proposes the development paths and zoning optimization strategies for agriculture in Shandong province.
