Ren Min Ri Bao· 2025-10-05 07:19
"天下大乱,此地无忧;天下大旱,此地有收"。在湖南新化的紫鹊界梯田流传这样一句民谚。天下梯田 何其多,紫鹊界有啥特殊?一是历史,二是规模,第三,要归功于其"技术含金量"。 打破"多头管理、权责分散"的状态,成立紫鹊界梯田管理机构,实现保护、规划、利用一体化运作。46 条1.6万米的小微水渠被修复,确保灌溉系统沿用传统技艺。1500亩抛荒梯田生态得到修复,核心生态 区实施封山育林,使区域水源涵养能力提升35%,让梯田生态系统回归"山青、水绿、田肥"的原始风 貌。 风景更美了,谁来看,怎么看?紫鹊界推出"沉浸式农耕体验"。游客们除了打卡观光,更能亲手参与插 秧、收割、打谷,做一天农夫。针对青少年的研学游,将梯田变成课堂,学生走进田间地头,在劳动中 了解"一粒米的前世今生",理解人与自然的和谐共生。为了让更多人"触碰"到梯田,"梯田守护者"认养 计划应运而生。一块块梯田"飘"上云端,通过小程序,认养人随时可以查看稻谷的生长,到了收获季 节,还能获赠田里产出的稻米。 金秋已至,正沿着山脚爬上山腰,将紫鹊界的稻子染成金黄。云上的梯田,即将为更多家庭带去丰收的 喜悦。 梯田皆依山就势而造,小如碟、大如池、长如带、弯如月… ...
