Salinity Potential of Western Sydney

This map depicts the distribution and potential severity of dryland salinity based on biophysical factors that are known to cause dryland salinity. The mapping shows four classifications of salinity potential:;\r\n1.Areas of Known Salinity ;\r\n2.Areas of High Salinity Potential ;\r\n3.Areas of Moderate Salinity Potential ;\r\n4.Areas of Very Low Salinity Potential ;\r\nThe map and accompanying guidelines are an extension of (and incorporate) the previous work, Draft Salinity Hazard Map for Western Sydney. They cover the Wianamatta Shales geological group on the Cumberland Plain, which essentially covers the area of Western Sydney, north to Windsor and south to Campbelltown.

本地图基于已证实可引发旱地盐渍化（dryland salinity）的生物物理因素（biophysical factors），呈现了旱地盐渍化的分布特征与潜在严重程度。本次制图共划分了四类盐渍化潜势（salinity potential）等级：
1. 已知盐渍化区域（Areas of Known Salinity）
2. 高盐渍化潜势区域（Areas of High Salinity Potential）
3. 中盐渍化潜势区域（Areas of Moderate Salinity Potential）
4. 极低盐渍化潜势区域（Areas of Very Low Salinity Potential）
本地图及配套指南是《西悉尼盐渍化风险草图地图》（Draft Salinity Hazard Map for Western Sydney）的延伸版本，且整合了该既往研究的相关内容。其覆盖坎伯兰平原（Cumberland Plain）上的怀亚纳马塔页岩地质组（Wianamatta Shales geological group），范围基本涵盖西悉尼全域，北至温莎（Windsor）、南至坎贝尔敦（Campbelltown）。
