Abstract

Water yield (WY) service is the cornerstone of ecosystem functionality. Predicting and assessing the impact of land use/land cover (LULC) changes on WY is imperative for a nation’s food security, regional economic development, and ecological environmental protection. This study aimed to evaluate the water yield (WY) service in Henan Province, China, using high-resolution (30 m) remote sensing land use monitoring data from four study years: 1990, 2000, 2010, and 2020. It also utilized the PLUS model to predict the characteristics of LULC evolution and the future trends of WY service under four different development scenarios (for 2030 and 2050). The study’s results indicated the following: (1) From 1990 to 2020, the Henan Province’s WY first increased and then decreased, ranging from 398.56 × 108 m3 to 482.95 × 108 m3. The southern and southeastern parts of Henan Province were high-value WY areas, while most of its other regions were deemed low-value WY areas. (2) The different land use types were ranked in terms of their WY capacity, from strongest to weakest, as follows: unused land, cultivated land, grassland, construction land, woodland, and water. (3) The four abovementioned scenarios were ranked, from highest to lowest, based on the Henan’s total WY (in 2050) in each of them: high-quality development scenario (HDS), business-as-usual scenario (BAU), cultivated land protection scenario (CPS), and ecological protection scenario (ES). This study contributes to the advancement of ecosystem services research. Its results can provide scientific support for water resource management, sustainable regional development, and comprehensive land-use planning in Henan Province.

中国河南省生态系统水产服务的时空动态及对未来土地利用情景的响应

产水量（WY）服务是生态系统功能的基石。预测和评估土地利用/土地覆盖（LULC）变化对水产量的影响对于国家粮食安全、区域经济发展和生态环境保护至关重要。本研究旨在利用四个研究年份的高分辨率（30 米）遥感土地利用监测数据，对中国河南省的水资源产量（WY）服务进行评估：本研究旨在利用 1990、2000、2010 和 2020 这四个研究年份的高分辨率（30 米）土地利用遥感监测数据，对河南省的水资源产量服务进行评估。研究还利用 PLUS 模型预测了四种不同发展情景下（2030 年和 2050 年）土地利用、土地利用变化和水产服务的演变特征及未来趋势。研究结果如下(1）从 1990 年到 2020 年，河南省的 WY 量先增后减，从 398.56×108 m3 增至 482.95×108 m3。河南省南部和东南部为高 WY 值地区，其他大部分地区为低 WY 值地区。(2) 不同土地利用类型的水源涵养能力从强到弱依次为：未利用地、耕地、草地、建设用地、林地和水域。(3) 根据河南省 2050 年的总 WY，对上述四种情景进行了从高到低的排序：高质量发展情景（HDS）、一切照旧情景（BAU）、耕地保护情景（CPS）和生态保护情景（ES）。本研究有助于推动生态系统服务研究。研究结果可为河南省水资源管理、区域可持续发展和土地利用综合规划提供科学支持。

期刊介绍： Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
