Abstract

This paper studies the litter properties of Moscow State University urban stands using the examples of birch, linden, and maple forests with a different type of care, varying from periodic care, regular care, and lack of care. Simplification of the vertical structure as a result of care increases the open space inside the stands, changing the degree of shading and wind regime. For park stands, the special role in litter formation belongs to lateral wind transfer and care regularity; these factors influence litter pool and fraction composition. The use of stand care is accompanied by the withdrawal of from 50 to 90% of the stocks of litter, which leads to decreasing recycling of organic matter and ash elements in urban ecosystems.

不同种植护理类型的城市生态系统凋落物特征

摘要

本文使用桦木、椴树和枫树林的示例研究莫斯科国立大学城市林分的枯枝落叶特性，这些森林具有不同类型的照料，包括定期照料、定期照料和缺乏照料。由于小心翼翼，垂直结构的简化增加了看台内的开放空间，改变了遮阳程度和风况。对于公园看台，凋落物形成的特殊作用属于侧向风转移和护理规律；这些因素影响垫料池和部分组成。使用看护伴随着 50% 到 90% 的枯枝落叶库存的减少，这导致城市生态系统中有机物质和灰分元素的回收减少。
