基于灰色关联度分析的土壤水盐动态变化研究
Investigation on Soil Water-Salt Dynamic Change Based on Grey Correlation Degree Analysis
依据多年观测资料与实地调查，应用灰色关联分析方法对洛惠灌区地下水矿化度、埋深与土壤含盐量之间的关系进行了系统分析，结果表明，地下水矿化度是影响土壤含盐量的主要因素，而地下水埋深对盐分的转移也起着重要的作用。通过对灌区地下水矿化度和地下水埋深同土壤含盐量之间的年际动态变化关系的进一步分析，初步判定洛惠渠灌区处于脱盐或相对稳定状态；由于地理位置、地形地貌、气候及人为等因素综合作用，可根据该灌区具体情况，充分利用地下水资源，有效的预防盐碱化发生和发展。

Accord to data have observed and investigated on-site for many years, the grey correlation analysis method is applied to detailed analyze the relations between groundwater mineralization, depth and soil salt content from the macroscopic, and its correlation degree is calculated. Results show that groundwater mineralization is the main factor of affecting soil salt content and groundwater depth also play an important role in transfer of salinity; then the annual dynamic changes relations between groundwater mineralization, depth and soil salt content is emphatically analyzed. It can be preliminarily determined that it is in desalination condition or in relative stable state in Luohui Trench Irrigation District; Because of the comprehensive action of factors such as geographical position、topography and geomorphology、climate、artificial etc, it could be made full use of groundwater resources and prevented the occurrence and development of salinization effectively according to the concrete conditions of Irrigation District.
