Based on lithology,geophysical data and test data,the authors divided karstification of northern Tarim Basin into three types(penecontemporaneous karstification,buried karstification,weathering karstification)and some subtypes.
本文以岩石学、地球物理资料及测试分析资料为基础,将塔北地区奥陶系碳酸盐岩古岩溶划分为准同生岩溶、埋藏岩溶、风化壳岩溶三大类及若干亚类。
Karst hydrosystem is likely to suffer damage from human improper activities not only in bare karst region or cover karst region but also in buried karst region because of its natural fragility and susceptible character.
对比研究埋藏型岩溶垄脊槽谷区岩溶水质变化与土地利用的关系可以看出,研究区水质20年来的变化以及水质的空间变异与土地利用有很大的相关性;其中集约化的农业耕作、炸石填土增加土地面积、利用落水洞排放污水和独特的微型稻田水位控制设施对岩溶地下水水质产生显著影响;这也表明人类活动已经对该区水文地球化学产生了区域性的重大影响。
