Abstract
Studying the agricultural spatial distribution characteristics of Jianghan Plain from 2000 to 2018 and its spatial-temporal transformation with ecological space and urban space is of great significance for optimizing the spatial structure of the country, enhancing the supply capacity of agricultural products, and ensuring food security. The research results show that during the period from 2000 to 2018, the agricultural spatial concentration in the area along the “Xiaogan-Jingzhou” link was relatively high, and the areas with large declines were mainly distributed in the flat areas between the Yangtze River and Han River; the space is continuously reduced by the occupation of ecological space and urban space, and ecological space and urban space have been improved respectively; agricultural space has been transformed into ecological space, and the largest urban space has been transformed. Ecological space has been transformed into agricultural space and urban space. Less urban space has been transformed into agricultural space and ecological space.

The research results show that during the period from 2000 to 2018, the agricultural spatial concentration in the area along the “Xiaogan-Jingzhou” link was relatively high, and the areas with large declines were mainly distributed in the flat areas between the Yangtze River and Han River; the space is continuously reduced by the occupation of ecological space and urban space, and ecological space and urban space have been improved respectively; agricultural space has been transformed into ecological space, and the largest urban space has been transformed
The analysis shows that in the past 18 years, agricultural space has been continuously occupied by ecological space and urban space and has declined; ecological space has been continuously occupied by urban space, it has increased due to the simultaneous occupation of agricultural space; urban space has shown an upward trend year by year
Summary
Agricultural space resources are the basic natural conditions for human beings to survive and develop. They are responsible for meeting people’s food needs and are the basic driving force for urban development [1] [2] [3]. Xing cultural spatial pattern is an important guarantee for national food security. It is of great significance for optimizing the national spatial pattern, enhancing the supply of agricultural products, and promoting the healthy development of cities [4] [5] [6]. This article analyzes the agricultural spatial pattern distribution and spatial-temporal evolution characteristics of the Jianghan Plain in different periods, and quantifies the mutual transformation between agricultural space, ecological space, and urban space in combination with the “three-zone space” background of the current land space planning, and analyzes and studies the driving force behind it
