Abstract:

Based on the rural residents' income data of 21 County-level administrative region in the Sanjiangyuan ecological function zone (SEFZ) from 2012 to 2019，this paper studied the impact of the natural geographical characteristics of the region on the income of farmers and herdsmen through the establishment of topographic-air quality degree, and the comprehensive use of exploratory spatial analysis and spatial econometric model. The results showed that: (1) the per capita disposable income of farmers and herdsmen increased from 4567.92 to 10417.56 yuan in the SEFZ, showing a spatial distribution characteristic of ‘high in the east and low in the west, high in the north and low in the south’, with spatial aggregation in some areas. (2) Geographical environment had an overall effect on the income of farmers and herdsmen through influencing their production and life, regional economic development, urban and rural resource allocation and government economic policies. (3) The Spatial Durbin Model showed that the income growth of farmers and herdsmen in a certain region would drive the adjacent region. The worse the topographic-air quality degree, the lower the income level of farmers and herdsmen in different regions. GDP growth was beneficial to increase the income of farmers and herdsmen in neighboring regions, while the improvement of industrial structure was beneficial to increase the income of farmers and herdsmen in this region. The modernization of agriculture and animal husbandry had little effect on the income growth of farmers and herdsmen. The increase of government expenditure could also promote the income growth of farmers and herdsmen in different regions.

Key words: income of farmers and herdsmen, topographic-air quality degree, Spatial Durbin Model, affecting factors, Sanjiangyuan ecological functional zone
