This project takes the example of Jiangsu Province on the eastern coast of China, which is economically developed and rapidly urbanising, with a significant multifunctional transformation of agricultural space. The project quantitatively evaluates the production function, living function, ecological function of rural land by establishing a multifunctional index system.Classify cities into tiers based on night-time light and population density data, and analyse the gradient differences in the transformation of rural land use functions. \

|
|
|
Objectives:\
|
|
|
|
Establishment of a system of quantitative indicators of multifunction in agricultural space, Collection and rasterization of relevant data for evaluation indicators, Evaluation of the level of multifunctional development of rural land, ...!\

|
|
|
To construct a multidimensional evaluation index system for RLUFs and identify the dominant land use function combinations (LUDFC). To incorporate the concept of an urban radiation gradient (URG) in delineating rural regions. To map the spatiotemporal transformation of LUDFC across different gradients in Jiangsu’s rural areas from 2000 to 2020. To analyze the gradient differentiation characteristics of rural responses under urbanization, providing theoretical insights and data support for urban-rural coordinated development and rural function optimization.\

Study area:\
|
|
|
|
This study examines Jiangsu Province, a rapidly urbanizing and economically developed region on China's eastern coast, as the research area, where rural land has undergone significant reconfiguration since 2000. This study investigates the multifunctional transformation of rural land in the province from 2000 to 2020 and its impacts by analyzing changes in rural land, excluding areas designated for urban, industrial, mining, and construction purposes...!\

Data,software, hardware:\
|
|
|
|
At present, the required data are below:
|
|
|
|
land use data at 100m resolution for the three periods of 2000, 2010 and 2020, which are mainly divided into arable land, forest land, grassland, urban, industrial and mining construction land, rural settlements, watersheds, and unused land, among which land use types. The spatial data needed in the quantitative evaluation of agricultural spatial multifunctionality include NDVI data, night light data, population density data, traffic data, soil data, DEM data, etc.; the statistical data needed include GDP and component data, urbanization rate data, etc.
