Soil and Land Resources of the Merriwa Plateau

This digital soil landscape product contains natural resource mapping for the Merriwa. The Merriwa Plateau is located in the upper Hunter catchment including hills of the Southern Liverpool Ranges; grading to gently sloped plateau around Merriwa. The project was funded by the National Partnership Agreement to provide improved soil and landscape information for this highly productive agricultural area. It has enabled more accurate and better quality Land and Soil Capability and Soil Fertility information to be available for future updates of Biophysical Strategic Agricultural Land (BSAL) mapping under the NSW Strategic Regional Land Use Policy (SRLUP). This resource information will also assist other decision making, planning and environmental modelling throughout the catchment.\r\n\r\nForty soil landscape map units have been described for the Merriwa Plateau. Each unit is an inventory of soil and landscape information with relatively uniform land management requirements, allowing major soil and landscape qualities and constraints to be identified. Soils are described using the Australian Soil Classification and the Great Soil Groups systems.\r\n\r\n__Related Datasets:__ The dataset area is also covered by the mapping of the Soil landscape 1:100 000 and 1:250 000 mapping series for the mapsheets of Dubbo , Singleton , Murrurundi and Blackville . Part of this area is also covered by the mapping of Hydrogeological landscapes of NSW .\r\n\r\n__Online Maps:__ This and related datasets can be viewed using eSPADE (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the SEED Map ; an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.\r\n\r\n__Reference:__ Office of Environment and Heritage, 2014, _Soil and Land Resources of the Merriwa Plateau_, NSW Office of Environment and Heritage, Sydney.

本数字土壤景观产品包含默里瓦（Merriwa）区域的自然资源制图成果。默里瓦高原（Merriwa Plateau）位于亨特流域上游，涵盖南利物浦岭丘陵地带，并向默里瓦周边的缓坡高原过渡。本项目由国家合作协议资助，旨在为这片高产农业区域提供优化后的土壤与景观信息，其产出的精准优质的土地与土壤承载力、土壤肥力信息，可用于依据新南威尔士州（New South Wales，简称NSW）战略区域土地使用政策（Strategic Regional Land Use Policy，简称SRLUP）开展的生物物理战略农业用地（Biophysical Strategic Agricultural Land，简称BSAL）制图更新工作。该资源信息还可助力该流域内的其他决策制定、规划与环境建模工作。

针对默里瓦高原，已划定40个土壤景观制图单元。每个单元均为土壤与景观信息的汇总清单，其土地管理需求相对统一，可用于识别主要的土壤与景观属性及限制因子。土壤分类采用澳大利亚土壤分类系统与大土类系统进行描述。

**关联数据集**：本数据集覆盖区域同时涵盖达博（Dubbo）、辛格尔顿（Singleton）、穆鲁伦迪（Murrurundi）与布莱克维尔（Blackville）四幅图幅的1:100000及1:250000比例尺土壤景观制图系列成果。该区域的部分范围还覆盖于新南威尔士州水文地质景观制图成果中。

**在线地图**：可通过eSPADE（新南威尔士州土壤空间可视化工具）查看本数据集及关联成果，该工具包含土壤剖面数据在内的全套土壤与景观信息。多数此类数据集均配有热链接土壤报告。另一可视化工具为SEED地图，可便捷查看本图幅区域内可获取的其他自然资源数据集（如植被相关数据）。
