This collaborative UK-China project proposes will establish a suite of Decision Support Tools (DSTs) that incorporate knowledge advances from the ongoing Phase 1 UK-China Critical Zone science research programme. With these advances, DSTs currently used in the UK and China will be adapted, expanded, tested and applied. The DSTs, data sets and decision outcomes will guide and evaluate site-specific innovation in soil and water management, and create roadmaps to scale up impact outcomes and plans to regional and national scale in China. The project will integrate the teams and research results of the 5 projects funded in Phase 1. Phase 2 will deliver immediate innovation in decision support methods and their application, and pathways to long-term impact and ODA outcomes: to restore ecosystems, improve soil fertility and water quality, improve farming livelihoods and improve food and water security. Impact delivery will focus on 5 critical zone observatories (CZOs) in China, established in Phase 1, which are located in regions with large-scale environmental and economic challenges related to degraded soil and water resources. 1. Hydro Karst CZO in SW China - land use and water quality linked to nutrient contamination of aquifers and surface waters in transmissive carbonate terrain2. Peri-Urban CZO in the Yangtze delta - soil contamination from urban atmospheric deposition and intensification of agricultural chemical use3. SPECTRA Karst CZO in SW China - Ecosystem degradation and karstic desertification linked with soil erosion and loss of soil fertility 4. Red Soils CZO - loss of soil fertility from intensification of agricultural production5. Loess CZO - ecosystem degradation under intensification of rural land useParticipatory research with stakeholders in China will identify the land, water and food demand conflicts that need be addressed in the regions of the CZOs. This KE is designed to avoid a recognised mismatch between the way DSTs are conceptualised by scientists and how DSTs may be most effectively used by stakeholders. Recent reviews of DSTs for land, water and food sustainability provide a platform for assessing the suitability of different DSTs to the challenges of China. The UK and China teams and stakeholders will identify the most promising DST approaches and test these using the data sets of the 5 CZOs. The outputs will be tested with a wider set of DST users and potential users. The outcomes will allow mapping DSTs and their suitability to address soil and water management challenges at the 5 CZO sites. This work will assess effectiveness of the DSTs across the scales of interest for stakeholder groups at the sites. This will include identifying sustainable practices, the scale at which the CZO and related measurements strengthen the evidence base and inform practices for management decisions, and how adaptations in a DST methodology would improve site-specific application. The project will apply national data sets on the geographic variability of soil and water resource demand and use patterns, and natural conditions of geology, soil, vegetation cover, climate and weather. Through engagement with regional planners, the project will design pathways to scale up the DST outcomes for application in regional-scale resource planning. The final stage will be synthesis of the adapted, applied and upscaled DST methods into practical guidance in how to deploy the DSTs in regionally specific contexts, the capabilities of different DSTs and applicability of DST outputs. The institutional partners in China will publish the guidance and organisations will be identified and trained as superusers to disseminate training. Superusers will conduct a series of regional workshops in China, led by Chinese partners, to create a network of users who are at the forefront of innovation in soil and water management planning and implementation.

这个中英合作项目建议建立一套决策支持工具（DSTs），该工具将纳入正在进行的中英关键区科学研究计划第一阶段的知识进步。随着这些进步，目前在英国和中国使用的dst将被调整、扩展、测试和应用。DSTs、数据集和决策结果将指导和评估具体地点的水土管理创新，并制定路线图，将影响成果和计划扩大到中国的区域和全国范围。该项目将整合第一阶段资助的5个项目的团队和研究成果。第二阶段将提供决策支持方法及其应用方面的即时创新，以及实现长期影响和官方发展援助成果的途径：恢复生态系统，改善土壤肥力和水质，改善农业生计，改善粮食和水安全。影响交付将集中在中国的5个关键区域观测站（czo），这些观测站位于与土壤和水资源退化相关的大规模环境和经济挑战地区。1. 中国西南水合喀斯特CZO——与传递型碳酸盐地形含水层和地表水养分污染相关的土地利用和水质[j]。长江三角洲城市周边CZO——城市大气沉降与农业化学品使用加剧对土壤的污染[j]。中国西南喀斯特CZO -生态系统退化和喀斯特沙漠化与土壤侵蚀和土壤肥力丧失的关系红壤CZO -农业生产集约化造成的土壤肥力损失与中国利益相关方的参与式研究将确定CZO地区需要解决的土地、水和粮食需求冲突。本指南旨在避免科学家对DSTs进行概念化的方式与利益相关者如何最有效地使用DSTs之间的公认不匹配。最近对土地、水和粮食可持续性发展技术的综述为评估不同发展技术对中国挑战的适用性提供了一个平台。英国和中国的团队和利益相关者将确定最有前途的DST方法，并使用5个czo的数据集对这些方法进行测试。这些产出将在更广泛的DST用户和潜在用户中进行测试。结果将允许绘制DSTs及其适用性，以解决5个CZO站点的土壤和水管理挑战。这项工作将为各地点的利益相关者团体评估可持续发展sts在不同利益范围内的有效性。这将包括确定可持续实践，CZO和相关测量加强证据基础并为管理决策提供实践信息的规模，以及DST方法的调整将如何改善具体地点的应用。该项目将应用关于土壤和水资源需求和利用模式的地理变异性以及地质、土壤、植被覆盖、气候和天气等自然条件的国家数据集。通过与区域规划者的合作，该项目将设计途径，扩大DST成果在区域规模资源规划中的应用。最后阶段将是将调整、应用和升级的DST方法综合为如何在区域具体情况下部署DST、不同DST的能力和DST产出的适用性的实际指导。中国的机构合作伙伴将发布指南，组织将被确定和培训为超级用户，以传播培训。超级用户将在中国举办一系列由中方合作伙伴领导的区域研讨会，以建立一个在水土管理规划和实施方面处于创新前沿的用户网络。
