数据包括西北内陆区各市级行政区现状年（2016年）的供水总量、污水处理量和再生水利用量；2035、2050年污水排放量和再生水量可供水量预测值。\n
2016年，西北内陆区各地污水年处理量大部分为500万立方米以下，新疆省会乌鲁木齐为西北地区污水处理量最大的市级行政区，达到10000万立方米以上，其次是新疆的克拉玛依、库尔勒、昌吉等地区以及甘肃省武威市和青海部分地区污水处理量较大，可以达到1000万立方米以上。与污水处理量分布特点相似，污水处理量大的区域再生水利用量大。然而新疆乌鲁木齐市利用量不足500万立方米，仅占污水处理量的百分之五左右，西北内陆区再生水利用量整体偏低，新疆西南部、内蒙片区和青海东部等地区尚未进行再生水回用。\n
2035年新疆、青海、甘肃和内蒙再生水供水潜力分别为62885万m³，13753m³，11428万m³，1205万m³；2050年新疆、青海、甘肃和内蒙再生水供水潜力分别为76562万m³，19604m³，18230万m³，1572万m³。2035年新疆、青海、河西内陆区污水排放量预测值分别为64515.45万m³，16450.8m³，13215.48万m³；\n

2.3再生水供需系统子模型\n
在城市再生水供需系统中，居民生活污水，部分工业废水和城市杂用尾水经城市污水处理厂和再生水厂净化处理后，可作为城市第二供水水源。\n再生水回用大多从集中式污水处理厂通过管道输送，利用方式主要是农业灌溉、市政杂用和城市生态用水。其中，二级出水加上混凝、砂滤、消毒等过程可以用于工业、市政和生活杂用水等方面；二级出水后经过深度处理可用于工业厂区的生产用水。从技术成本角度看，二级出水被认为可以满足除新鲜蔬菜外的农作物灌溉的需要，但二级出水从污水处理厂到农田管网建设投入大、收益低，所以城市再生水利用时不考虑农业灌溉。各项目需水量的计算均以面积或者数量乘以相应的单位用水配额得到。", "ds_quality": "

The data include the total water supply, wastewater treatment volume and recycled water usage of each municipal administrative region in the Inland Northwest Region in the current year (2016); and the projected values of wastewater discharge volume and recycled water availability in 2035 and 2050.\n
In 2016, most of the annual sewage treatment volume across the Inland Northwest Region was less than 5 million cubic meters, and Urumqi, the capital of Xinjiang Province, was the largest municipal administrative region in the Northwest Region, reaching more than 10,000,000 cubic meters of sewage, followed by Karamay, Korla, and Changji regions in Xinjiang, as well as Wuwei City, Gansu Province, and parts of Qinghai Province, where sewage treatment volume is is large and can reach more than 10 million cubic meters. Similar to the characteristics of the distribution of sewage treatment volume, the region with large sewage treatment volume has a large amount of recycled water. However, the utilization of Urumqi City, Xinjiang is less than 5 million cubic meters, accounting for only about five percent of the sewage treatment volume, the inland northwest region of reclaimed water usage overall low, southwest Xinjiang, Inner Mongolia area and eastern Qinghai and other areas have not yet reclaimed water reuse.\n
2035 Xinjiang, Qinghai, Gansu and Inner Mongolia recycled water supply potential of 62885 million m³, 13753 m³, 114.28 million m³, 12.05 million m³; 2050 Xinjiang, Qinghai, Gansu and Inner Mongolia recycled water supply potential of 7656.2 million m³, 196.04 million m³, 182.3 million m³. 15.72 million m³. In 2035, the projected sewage discharge in Xinjiang, Qinghai and Hexi inland area is 645,154,500 m³, 164,508 m³ and 132,154,800 m³, respectively;\n
In 2050, the projected sewage discharge in Xinjiang, Qinghai, and Hexi inland areas were 77244.95 million m³, 199,912,000 m³, and 200681,000 m³, respectively.

2.1.Socio-economic sub-modeling\n
a. Population growth\n
The number of people in the city directly affects the amount of water used for residential purposes. A Malthusian model was used to estimate population growth due to the short forecast period.\n
X=X₀×e^q×t\n
where X represents the number of population, X₀ represents the initial annual population, t represents the model simulation year, and q represents the natural population growth rate.\n
b. Industry, economic growth\n
Its annual growth rate is obtained using a one-way linear regression model, and then substituted into the SD model to simulate the system change.\n
2.2 Sub-model of tap water supply and demand system\n
a. Residential domestic water demand\n
According to the per capita living comprehensive water consumption and water consumption population to get the residents living comprehensive water demand.\n
b. Industrial water demand\n
The overall water demand is calculated based on the water demand per unit of value added of output and the growth rate of industrial output.\n
c. Ecological water demand\n
The model in this paper uses reclaimed water to recharge the ecological environment\n
2.3 Sub-model of reclaimed water supply and demand system\n
In the urban reclaimed water supply and demand system, residential sewage, part of the industrial wastewater and urban miscellaneous tail water can be used as the second source of urban water supply after purification and treatment in urban sewage treatment plants and reclaimed water plants.\nMost of the reclaimed water reuse from centralized wastewater treatment plant through the pipeline, the utilization is mainly agricultural irrigation, municipal miscellaneous use and urban ecological water. Among them, the secondary effluent with coagulation, sand filtration, disinfection and other processes can be used for industrial, municipal and domestic miscellaneous water use, etc.; the secondary effluent can be used for the production of water in industrial plants after deep treatment. From the perspective of technical cost, the secondary effluent is considered to meet the needs of crop irrigation except for fresh vegetables, but the construction of the secondary effluent pipeline network from the wastewater treatment plant to the farmland has high investment and low return, so agricultural irrigation is not considered in the utilization of urban reclaimed water. The calculation of water demand for each project is obtained by multiplying the area or quantity by the corresponding unit water quota.", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 0, "license_type": "CC BY 4.0", "doi_reg_from": "reg_local", "cstr_reg_from": "reg_local", "doi_not_reg_reason": null, "cstr_not_reg_reason": null, "is_paper_in_submitting": false, "ds_topic_tags": [ "西北内陆区", "污水排放量", "再生水可供水量" ], "ds_subject_tags": [ "地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "青海片区", "新疆片区", "甘肃片区", "内蒙古片区" ], "ds_time_tags": [ 2016, 2035, 2050 ], "ds_contributors": [ { "true_name": "蒋晓辉", "email": "xhjiang@nwu.edu.cn", "work_for": "西北大学", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "敏玉芳", "email": "myf@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "ds_managers": [ { "true_name": "蒋晓辉", "email": "xhjiang@nwu.edu.cn", "work_for": "西北大学", "country": "中国" } ], "category": "生态" }
