At 29, Shi belongs to a new generation of desert-control workers equipped with drones, machines and remote irrigation systems. An earth auger can now do in a day what once required about 200 laborers, while a single phone can control drip irrigation across more than 1,000 mu (about 66.67 hectares) of woodland.
For the older Shi's generation, the challenge was getting trees to survive in moving dunes. For the grandson, it is figuring out how to make those forests healthier and more resilient for decades to come.
Their story captures a broader shift in desert control along the southern edge of the Maowusu Desert in northwest China's Shaanxi Province: turning shifting sand into forest was only the beginning.
In 1986, Shi Guangyin, Shi Jianyang's grandfather, led more than 300 villagers into Langwosha, a sandy area in Dingbian County in Yulin City. He had raised 60,000 yuan (about 17,377 U.S. dollars at the time) by selling his family's 84 sheep and borrowing from relatives and banks to contract 3,500 mu of barren sandy land.
The early setbacks were severe. Strong winds destroyed about 90 percent of the saplings in the first year, and about 80 percent of those planted the following year failed to survive.
After seeking advice from forestry experts, Shi and the villagers laid out checkerboard-shaped barriers on windward slopes to hold the sand in place, then planted trees, shrubs and grasses within them. Sapling survival rates rose to about 80 percent.
Over the next four decades, Shi and those working alongside him treated 250,000 mu of sandy and saline-alkali land, with more than 53 million trees and shrubs taking root.
Greening the Maowusu Desert is part of a much larger national undertaking. It is one of the three major battlefronts of China's Three-North Shelterbelt Forest Program, a decades-long effort to curb desertification across northern China.
China has made desertification control a national ecological priority. Since 2023, the country has stepped up efforts under the program, with greater emphasis on systematic restoration and on consolidating earlier gains.
Decades after the first trees took root, a new challenge emerged. Poplars planted decades ago for their rapid growth began reaching the end of their life cycle, with large numbers of trees dying, while forests dominated by a single species were more vulnerable to pests and disease.
Making a forest was one challenge. Keeping it healthy for another generation is another.
Shi Jianyang grew up watching his grandfather and father work to hold back the sand. His father, Shi Zhanjun, spent years planting trees alongside Shi Guangyin before dying in a road accident in 2008 while transporting saplings.
As a boy, Shi Jianyang sometimes resented the work that had taken his father. He spent summer holidays in makeshift tents in the sandy land, eating meals gritty with sand. During planting season, his father would return home with painful blisters in his mouth.
Yet he eventually chose forestry himself.
After studying forestry technology in university, Shi returned home in 2020 and began working in desert control. His team, initially made up of just seven or eight young locals, later brought in university graduates with expertise in soil science, landscaping and pest control.
The younger generation faced a different question: not simply how to make trees survive, but how to make a forest last.
Shi and his team spent more than 40 days in a 5,000-mu woodland setting up sample plots, measuring rainfall, studying soil microorganisms and tracking tree lodging. They proposed renewing aging forests with better-planned forest structures and expanded the planting of Mongolian pine, a long-lived evergreen species that had been successfully tested locally.
To date, about 50,000 mu of land has been planted with Mongolian pine. As some trees fail to survive and require replacement in subsequent planting seasons, the cumulative area of planting operations has reached about 65,000 mu.
Technology has also changed daily work. Drones patrol forests from the air, mechanized equipment dig planting pits, and irrigation can be managed remotely. Sapling survival rates, which Shi Guangyin's generation had raised to about 80 percent through improved sand-control and planting methods, have climbed further to about 92 percent with greater mechanization and more precise management.
Shi said the changes can be felt on the ground. Strong sandstorms have become rare, winds are weaker inside the forest, and the ground stays moist longer after rain. Summer days beneath the trees also feel cooler, while morning dew appears more often. The changes lead him to rethink desert control.
His approach also reflects a broader effort in China's desert regions to link ecological restoration with local livelihoods, giving communities a stronger economic stake in protecting restored land.
With his grandfather's support, Shi and his team have been looking for ways to make better use of the restored land as ecological conditions improve. They have developed potato seedlings suited to sandy soil, promoted greenhouse farming, and set up a livestock cooperative, while increasingly growing potatoes, watermelons and peppers on land once prone to losing water and nutrients.
Shi has also turned to livestreaming e-commerce to market potatoes and other local farm produce, while developing forest-based health and leisure projects. More than 2,000 local residents have seen their incomes rise steadily as farming, livestock breeding and other businesses have developed.
"We used to fear the sand and keep away from it. Now we understand it and know how to make use of it," Shi Guangyin said. "Today, there are opportunities to make a living everywhere in this sandy land."
Across Yulin, forest coverage has risen from 1.8 percent in 1949 to 34.8 percent, while shifting dunes that once encroached on villages have been brought under control.
For Shi Jianyang, however, the green landscape is not proof that the work is finished. "Planting a tree is not difficult," he said. "The difficult part is looking after it for decades."
The grandfather generation learned how to stop the sand. The young generation is learning how to make what grew there last.
。 过去的6天时间里，又有4个新台风陆续生成。台风“简拉维”24日中午在福建泉州沿海登陆，台风“紫檀”一直“滞留”在北部湾，给广西等地带去强降雨。台风“艾莎尼”和台风“沙德尔”则正在行进中。
B | 四个台风将会影响哪些地区?今年台风为啥这么多?面对已经出现的灾害风险，广西又在如何抢险救灾?本期《新闻1+1》带来分析解读。 四个台风同存在、同时活跃是否常见? 中央气象台首席预报员 周冠博：四个台风共舞在历史上来说是比较罕见的，但也不是绝无仅有。
C | 目前“紫檀”和“简拉维”互旋效应比较明显。
D | “艾莎尼”和“沙德尔”由于距离比较远，“沙德尔”的体积比较小，强度比较弱，所以它们互旋的情况比较微弱。但不管怎么样，当有多个台风同时存在的时候，会给每个台风的路径和强度预报都带来极大的困难。所以它们的未来走向，以及强度的发展的不确定性都是比较大的，要密切关注不断更新的台风预警信息。 四个台风最新变化一览 “简拉维”停止编号 中央气象台于24日晚8点将“简拉维”停止编号，但这不意味着它带来的影响减弱了。由于“简拉维”尾部大量季风云团涌入，福建中部沿海的水汽特别丰沛，再加上地形抬升的作用，未来的几天依然会受到残余涡旋的影响，也会给华东地区带来比较明显的降雨影响。

“紫檀”在北部湾打转
目前“紫檀”虽然没有登陆广西，但是从25日开始它将以5-10公里每小时的速度向偏北方向移动，逐渐向广西，以及广东的雷州半岛西侧靠近，由于它在同一个地方不断打转，风雨的叠加效应特别明显。 “艾莎尼”对“沙德尔”强度和路径发展会有一定影响
相较于“沙德尔”，新编号的“艾莎尼”强度比较弱，纬度又比较靠南，所以它们的距离比较远，目前不考虑互旋以及吞并的情况。但是随着“艾莎尼”不断向北移动，它停止编号之后的残余涡旋就会给“沙德尔”的强度和路径发展造成一定的影响。
“沙德尔”26日前后进入东海
“沙德尔”经过远洋西行之后，从广阔的西北太平洋上吸收更多的能量和水汽，所以它在26日进入我国东海之前，一直是维持超强台风的强度，甚至继续增长。26日移入我国之后，由于海温切变的影响，“沙德尔”强度有一定的不确定性。目前它的直径是比较庞大的，水汽也特别充沛，所以它将直面我国华东沿海地区，要密切防范“沙德尔”登陆时带来的强风降雨的影响。 今年台风数量较历史同期多9个，是什么原因?
周冠博：最主要的原因就是今年正处于一个超强的厄尔尼诺年，从今年的5月中旬开始，赤道中东太平洋的海温在持续飙升，强厄尔尼诺年会造成西北太平洋以及南海地区生成台风的个数偏多，强度也会偏强。随着海温继续飙升，影响和登陆我们国家的台风会明显偏多，偏强。据国家气候中心的统计，在9到11月，台风个数依然会有8-10个，其中3-5个会登陆或直接影响我国。 强降雨给北江乡造成什么影响?
总台记者 邓君洋：宁明县的北江乡、板棍乡、那勘镇、海渊镇发生了严重内涝，出现了断电、断路、断网、断水的情况，四个乡镇的村民受灾。北江乡大约有1.3万多人，大多数人在内涝发生之前就已经得到了预警预报提前转移了。县城有应急转移的安置点，同时有些村民也会到县城投靠亲友。目前村屯里面有一些行动不便但是家里有人照顾的老人，或者是一些即将要开学的学生，他们不想转移到太远的地方，那里还是有一些备用的物资供应，每天乡政府统计物资需求进行运送。 北江乡抢险救灾工作最新进展
邓君洋：北江乡受灾村落已经处在内涝之中了，从路边进村，进入到北江乡政府所在地大概需要一个小时左右，这一段路已经分不清是河道还是甘蔗地了，内涝积水很浑浊。但是我们隐约可以看到长高的甘蔗叶子，基于村干部反映，当地的甘蔗已经长到2-3米，说明内涝还是比较深的。
F | 应急救援人员主要是把医护人员、乡政府的轮值干部、电力救援人员，还有一些救援物资送进受灾的村落，再把一些轮班的干部、需要及时就医的村民 运送出来，整个过程还是比较顺利的。
