查询词典 dry-pipe system

An experiment was carried out in the greenhouse using a three-compartment rhizobox system to study effects of inoculation of arbuscular mycorrhizal fungi Glomus etunicatum, Glomus intraradices and Glomus mosseae on Festuca rubra and Agrostis hugoniana, and soil environment.

Brought forward and reasoned the forming mechanism of Maowusu sandy land. Based on the analysis of the development of Holocene rivers and related loess and windsandy geomorphology, the paper put forward the forming mechanism of Maowusu sandy land as follows: while the climate became dry, the exterior channels extended backwardly and cut through the remained lake system of ancient Hetao lake. This resulted in the rapid discharge of underground water. The vegetation living on this water resource was destroyed completely. Then the sand began to form.

对毛乌素沙地的形成机制进行了新的探索基于对过渡地带全新世河流及其相关的黄土和风沙地貌发育、土地利用变化等分析，提出毛乌素沙地的形成机制：在气候变干的同时，外流河谷溯源延伸，切穿了长城以北河套古湖残遗湖系，使地表地下水迅速外泄，原靠湖系水资源维系的生长在河套古湖湖滨沙堤形成的沙地上的非地带植被的生存条件被彻底摧毁，而起沙。
