粮食主产区耕地生态安全动态评价及农技推广的研究进展

Research Progress of Dynamic Evaluation of Ecological Security for Farmland in Main Grain Production Areas and Agricultural Technology Promotion

以粮食主产区为研究对象,探讨了耕地生态安全的动态评价方法,构建了初步的指标体系,应用多种评价模型,精确地模拟生态系统的变化趋势。提出的不同地域和生态系统类型的耕地生态安全动态评价方法、发展决策支持系统、改进数据收集和处理技术或将成为未来一段时期的研究重点。研究强调了农技推广在粮食主产区耕地生态安全动态评价中的重要作用以及未来的研究方向和挑战。

Taken main grain production areas as object the dynamic evaluation methods for ecological security for farmland was explored and a preliminary indicator system was established,various evaluation models were applied to simulate accurately the changes in the ecosystem.Proposed dynamic evaluation methods for ecological security for farmland in different regions and ecosystem types,development of decision support systems and improvement in data collection and processing techniques were identified as future research priorities.The crucial role of agricultural technology promotion in the dynamic evaluation of ecological security for farmland in main grain production areas was emphasized,and future future research directions and challenges were proposed.
