【环球网科技综合报道】9月14日消息，近日，中国科学家对月壤的研究更进一步——月球上不仅有水，而且存在高含量水。    (ECNS) -- Solar panels are appearing above more and more farms across China as the country looks for new ways to pair renewable energy with agricultural production.     A rooftop solar project at a large dairy farm in Anhui Province began operating in July, covering 560,000 square meters of cattle barn roofs without taking up any additional land.        The project can generate up to 300,000 kilowatt-hours of electricity a day and is expected to produce about 80 million kilowatt-hours a year, according to Xiao Jun, who heads the project. The farm houses about 40,000 cattle at a single site, he said, making it the largest in Asia to carry rooftop solar. The panels also help keep the barns cooler.    The project is part of a broader push in Anhui to combine solar power with farming. A hybrid fishery and solar project with a total investment of 514 million yuan (about $71 million) has begun construction in Hefei, according to the local government.    In Guangde, panels have been installed across nearly 600,000 square meters of tea plantations, generating about 136 million kilowatt-hours of green electricity a year, a representative of the project said.    The trend is spreading nationwide as local governments and businesses look for more efficient ways to use land and other resources. A report released in February projected that China's total solar power generation capacity would grow by about 25% in 2026.    Policy support is growing alongside it. The Renewable Energy Development Plan for the 15th Five-Year Plan period calls for wider use of distributed renewable energy in industrial, commercial, transport, building, and agricultural settings.    The sector continued to expand in the first half of 2026. The National Energy Administration said renewable energy accounted for 60.7% of China's total installed power capacity, with wind and solar making up nearly half.    The growth in solar applications is reshaping the photovoltaic industry itself. Industry experts say competition is shifting away from scale and price toward efficiency, technological innovation, and integrated applications.    For agriculture, researchers said "solar-plus" projects could extend the reach of photovoltaic power while keeping land in productive use.     (By Helen Mo & intern Liu Shuangjing)                    。中国科学院官微发文称，地球化学研究所科研团队对嫦娥五号月壤样品开展研究，通过红外光谱和纳米离子探针分析，发现嫦娥五号矿物表层中存在大量的太阳风成因水。该研究证实了月表矿物是水的重要储库，为月表中纬度地区水的分布提供了重要参考。

B | 据悉，这一成果日前在国际学术期刊《自然·通讯》发表。根据科研团队的估算，太阳风质子注入为嫦娥五号月壤贡献的水含量至少为170ppm，相当于每吨月壤中至少含有170克的水。而今年1月份首次在月壤中发现有水时，测算的数据为每吨月壤中约有120克的水。这样一看，对比就很明显了，也就是为什么将嫦娥五号月壤"水"判定为高含量水。证实了月球有水，那么这些水又是从何而来的呢？ 据介绍，我国科研团队在今年1月份首次在月壤中发现有水时，发布了一组数据。

C | 根据研究显示，1吨月壤中约有120克水，1吨岩石中约有180克水。并且结合样品分析，月壤中的水绝大部分是来自于太阳风的贡献，岩石中多出来的水则可能代表了月球内部水。据报道，在今年6月份，我国科研团队还发现嫦娥五号着陆区月壤中明显含有羟基形式的“水”，但平均含量较低。同时研究表明，嫦娥五号月壤样品中肯定存在来源于月球内部的原生水。研究团队对嫦娥五号月球样品的实验室分析，发现了至少一种含水矿物：羟基磷灰石，证明了嫦娥五号月壤样品中存在来自岩浆结晶过程的“水”，说明“水”在月球晚期岩浆活动过程中不仅存在，而且可能起到了非常重要的作用。
