The spillover effect of a new agricultural technological innovation leads to its spatial diffusion with various characteristics, which affects the economic and social development of regional agriculture and farmers' welfare. Understanding spatiotemporal characteristics of technology diffusion is essential for obtaining basic information to manage this innovation in an effective way. Here, we investigated the diffusion pattern of the integrated rice-crawfish farming system, which is an emerging agricultural production in Jianghan Plain of China. Based on time-series Landsat images, we introduced CART classification algorithm and simple non-iterative clustering method to optimize the object-based water difference method and mapped the distribution of rice-crawfish farming from 2013 to 2019. We analyzed the characteristics of diffusion from aspects of area extent, spatial aggregation, and spatial interaction. We found that the rice-crawfish farming system showed a nonlinear expansion pattern from 2013 to 2019. It was expanded from a few hotspots to an extensive area in surrounding areas, with highest density distributed in the middle and southeast of Jianghan Plain. The spatial distribution of the adopted technology had characteristics of high aggregation at certain directions, with the core moving from the middle to southeast. Two motivative regions, Qianjiang and Jianli, respectively promoted the speed and extent of rice-crawfish technology diffusion at the early stage and late stage. Policy incentives, community effects, and industry chains effectively facilitated the adoption and diffusion of rice-crawfish farming system at both of individual level and regional level. Our study revealed the diffusion process and common characteristics of the new technology, which highlights the importance of information exchange and the radiation effect of the core area for technology adoption. The results not only provide essential data and knowledge for understanding the development condition and conducting relative research, but also give evidential references for decision-makers for efficient management of the technology at early diffusion stage.
