摘要:以较低的生态代价获得较高的农业生产能力是目前气候变化背景下农业发展的目标。发展“资源节约、生产高效、生态友好”的现代农业, 应当成为新时期以绿色发展为主基调的农业现代化建设和发展中需要坚持的基本原则和方向。农业生态系统具生产和生态两大功能, 坚持生态优先, 在追求生态效益的同时, 实现更加长久的生产效益, 是破解可持续发展瓶颈的重要手段。基于粮食生产与生态压力转移的区域间耦合与系统优化, 解析区域性生产生态潜力的变化趋势; 发展生态农业, 建设无废弃物乡村, 对实现农业现代化和可持续发展具有重要意义。Abstract:To obtain higher agricultural production capacity at a lower ecological cost, the development of modern agriculture with resource conservation, efficient production, and ecological friendliness should become a basic principle and direction to be adhered to in agricultural modernization and development, with green development as the main tone in the new era. Agricultural ecosystems have two major functions: production and ecology. Adhering to ecological priorities and achieving more longterm production benefits while pursuing ecological benefits is an important mean of overcoming bottlenecks in sustainable development. Based on interregional coupling and system optimization of grain production, analyzing ecological pressure transfer and changing trends in regional production and ecological potential are important for agricultural modernization. The development of ecological agriculture and construction of waste-free villages are of great significance for the realization of agricultural modernization and sustainable development.
