A simple formula to calculate the width of hydrological buffer zones between drained agricultural plots and nature reserve areas

This paper presents new formulae to calculate the width of a buffer zone between a drained agricultural plot and a nature reserve area. These formulae are based on the classical Dupuit-Forchheimer assumptions and take into account the position of the impervious layer. With basic meteorological and agrological inputs, the proposed equations can be used to determine the length of the depression zone during watertable drawdown due to underground drainage. Calculating the required width of protection belts around peatland reserves is a typical and common application of the formulas presented in this paper.     

基于人与自然和谐共生的生态农业振兴模式与实践研究

生态农业是推进生态振兴与农业振兴双重目标实现的有效路径，大力发展生态农业是对“人与自然和谐共生”生态文明思想的科学实践。本文以“人不负青山，青山定不负人”生态理念的践行者之一——秦巴山区忠诚村为实证案例，运用文献研究和市场调研相结合方法，总结分析忠诚村“四主体三联三生”生态农业振兴模式、主要做法以及经验启示，并针对性提出发展建议，旨在为秦巴山区或同类地区发展生态农业和促进乡村产业振兴提供实例参考和发展借鉴。
