HUN AWRA-R Irrigation Area Extents and Crop Types v01
收藏资源简介：
## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nTabulated data with information on crop types and areas in each river reach in the Hunter river system model. This dataset was derived by the Bioregional Assessment Programme from existing catchment land use data obtained from the Australian Bureau of Agricultural and Resource Economics and Sciences.\n\n## **Purpose** \n\nThe AWRA-R river model needs details of irrigated areas and crop types in each river reach in which irrigation is present in order to determine areal extent and crop factors of the most common crop types .\n\n## **Dataset History** \n\nAreas and crop types are obtained from the Catchment scale Land Use Management (CLUM). The dataset was clipped using catchment boundaries defined by the AWRA-R modelling domain and the information summarised by reach in order to determine crop types and associated crop factors . Irrigation areas are determined using the first level classification in the CLUM dataset which describes the main land use type. Crop types were determined from the third level classification, which provides detailed information on crop types.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) HUN AWRA-R Irrigation Area Extents and Crop Types v01.

## 摘要 本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多个源数据集生成。源数据集信息详见本元数据声明的“谱系”字段，生成本派生数据集的过程则记载于“历史”字段。 本数据集为表格化数据，包含亨特河水系模型中各河段的作物类型及种植面积信息，由生物区域评估计划基于澳大利亚农业与资源经济科学局（Australian Bureau of Agricultural and Resource Economics and Sciences）提供的现有流域土地利用数据派生而来。 ## 用途 AWRA-R河流模型需要各灌溉河段的灌溉面积及作物类型详情，以确定最常见作物类型的分布范围和作物系数。 ## 数据集历史 作物面积与类型数据来源于流域尺度土地利用管理（CLUM）数据集。研究人员利用AWRA-R模型域定义的流域边界对数据进行裁剪，并按河段汇总信息，以确定作物类型及相关作物系数。灌溉面积通过CLUM数据集的一级分类（描述主要土地利用类型）确定，作物类型则通过提供详细作物信息的三级分类确定。 ## 数据集引用 生物区域评估计划（2016）。HUN AWRA-R灌溉面积与作物类型v01。生物区域评估派生数据集。查阅日期：2019年3月13日，网址：http://data.bioregionalassessments.gov.au/dataset/90013748-6247-47ad-bddb-07a9c2d857cd。 ## 数据集溯源 * **派生自** [吉普斯兰项目边界](https://data.gov.au/data/dataset/27413de5-d13a-4231-ac79-fc77f4cbb5f7) * **派生自** [生物区域评估区域v04](https://data.gov.au/data/dataset/e8a2d577-c5c5-4e2c-b0fa-53e4b2d4a034) * **派生自** [国家地表水站点Hydstra](https://data.gov.au/data/dataset/f7edc5e5-93ee-4527-bed5-a118b4017623) * **派生自** [2010年自然资源管理区域](https://data.gov.au/data/dataset/1d54e38f-4051-4f0c-a350-c7dbd8eba65b) * **派生自** [生物区域评估区域v03](https://data.gov.au/data/dataset/96dbf469-5463-4f4d-8fad-4214c97e5aac) * **派生自** [HUN AWRA-R校准流域v01](https://data.gov.au/data/dataset/d419aae0-1cb3-48a8-82de-941398a80e3a) * **派生自** [生物区域评估区域v05](https://data.gov.au/data/dataset/25f89049-839d-4736-bd81-97d8e8a40f8e) * **派生自** [HUN AWRA-R校准节点v01](https://data.gov.au/data/dataset/f2da394a-3d08-4cf4-8c24-bf7751ea06a1) * **派生自** [新南威尔士州流域管理局边界（20130917）](https://data.gov.au/data/dataset/0dc4272e-c081-4ed4-9645-aa336ffacd85) * **派生自** [生物区域评估计划-澳大利亚流域尺度土地利用（2014）](https://data.gov.au/data/dataset/6f72f73c-8a61-4ae9-b8b5-3f67ec918826) * **派生自** [生物区域评估区域v01](https://data.gov.au/data/dataset/0fd0d820-30b3-451f-a126-a50040426999) * **派生自** [生物区域评估区域v02](https://data.gov.au/data/dataset/e414b1b3-c42e-42e9-9cc4-2093054aa35f) * **派生自** [GEODATA 9秒数字高程模型与D8流向栅格（版本3，2008）](https://data.gov.au/data/dataset/ebcf6ca2-513a-4ec7-9323-73508c5d7b93) * **派生自** [GEODATA TOPO 250K系列3](https://data.gov.au/data/dataset/a0650f18-518a-4b99-a553-44f82f28bb5f) * **派生自** [维多利亚州-无缝地质图（2014）](https://data.gov.au/data/dataset/2872d02e-66cb-42b6-9e5a-63abc8ad871b) * **派生自** [地质省-完整范围](https://data.gov.au/data/dataset/0a064b3b-2a1e-4672-80d9-03333be67aad) * **派生自** [GEODATA TOPO 250K系列3（文件地理数据库格式，.gdb）](https://data.gov.au/data/dataset/96ebf889-f726-4967-9964-714fb57d679b)
