牲畜饲养结构的时空分布特征及驱动因素
Spatiotemporal distribution characteristics and driving factors of livestock feeding structure:A case study in Ningxia
摘要
Abstract
Animal husbandry is a crucial industry that significantly impacts the national economy and people's livelihoods.Its importance extends to the economy,environment,and food safety.Despite a continuous increase in overall animal production in China in recent years,two problems remain:animals are "large but not strong" and "abundant but not excellent".This study focuses on the livestock feeding structure,with aims to explore its temporal and spatial distribution characteristics as well as the driving factors.This research holds substantial value for guiding the rational distribution of resources and ensuring the sustainable development of animal husbandry in China.First,the temporal distribution characteristics of effective feeding amount and feeding structure of livestock in Ningxia in 1978-2020 were analyzed.Then,the spatial distribution characteristics of livestock feeding structure were assessed using coefficient of variation and standard deviation ellipse methods.Finally,the core driving factors influencing the spatial differentiation of livestock feeding structure were identified by applying the GeoDetector model.The main findings were as follows:1) The livestock feeding structure in Ningxia significantly changed around 2002 with a noticeable increase in the proportion of cattle and sheep and a decrease in the proportion of pigs.2) The proportion of cattle,sheep,and pigs showed spatial differentiation,but each exhibited a distinct trend of spatial heterogeneity.3) The proportions of cattle,sheep,and pigs displayed a shift from south-north distribution to northeast-southwest distribution.The regions with high proportions of cattle and sheep showed trend of expansion.4) The core driving factors influencing the proportion of cattle were natural resource conditions and socio-economic conditions and policies.The core driving factors influencing the proportion of sheep were socio-economic conditions and policies.However,the proportion of pigs was only affected by socio-economic conditions.Interactions among most of these core driving factors enhanced the spatial differentiation of livestock feeding structure.关键词
