构建新型气象为农服务体系 我国启动新一轮农业气候资源普查和区划

Core Viewpoint - The Chinese meteorological department will focus on food security by enhancing agricultural climate resource surveys and zoning, aiming to integrate meteorology into crop yield improvement actions by 2026 [1][3]. Group 1: Agricultural Climate Resource Survey and Zoning - A new round of national agricultural climate resource surveys and zoning has been fully initiated, with completion expected by 2029, including detailed surveys at national, provincial, municipal, and county levels [3][4]. - The agricultural climate zoning work will be progressively advanced, with a focus on major agricultural categories and crops [3][4]. Group 2: Impact of Climate Change on Agriculture - Climate change has increasingly affected agricultural production and food security, leading to challenges such as shifting planting boundaries and increased pest issues [4][7]. - The need for a scientific approach to agricultural climate resource surveys and zoning is emphasized to improve resource utilization efficiency and mitigate agricultural meteorological disasters [4][8]. Group 3: Characteristics of Agricultural Climate Resources - China's agricultural climate resources are diverse, with significant regional differences and a high impact from meteorological disasters [7]. - Recent trends show an increase in heat resources, while water resources are decreasing in certain regions, and light energy resources are increasing towards the northwest [7]. Group 4: Methodology for Surveys and Zoning - The current round of surveys and zoning will utilize advanced technologies such as geographic information systems and remote sensing to achieve precision at kilometer and even hundred-meter levels [8]. - The surveys aim to clarify the distribution characteristics of agricultural climate resources and propose strategies for efficient utilization and risk prevention [8].
