阅读下面的文字，完成下列小题。

    “原乡”是早年台湾客家人对于大陆故乡的称呼，原意是指一个宗系之本乡，换言之，原乡是指祖先未迁移前所居住的地方。“原”小篆字体为“0”，像泉水从山崖里涌出来。“乡”字甲骨文为“0”，像二人对食形，本义是用酒食款待别人，后引申为“乡村”、“自己生长的地方或祖籍”两种解释。所谓“原乡”即“原色本乡”，意味着传承祖先的历史记忆和原味生态环境。

    原乡规划理论的提出，是基于人们对人类工业化、城市化进程中，以发展大城市和大力开发经济为指导思想来引导规划所产生的担忧，尤其是中国在新农村建设和城乡统筹过程中，大量村落被毁，村民集中在社区楼房居住所表现出来的新农村的“城市化运动”，离“原乡”的本意越来越远，这样的规划在毁掉城市之后又将毁掉美丽的乡村。于是，原乡规划理论应运而生。

    原乡规划借鉴老庄哲学顺应自然的“无为自化”思想，强调在规划过程中尊重自然，尊重景观本色，尊重乡村本色，尊重自然规律，以实现自然境域下人们生活与生产的原真性，以“道法自然”、“天人合一”为规划的最高境界。

    近年来，乡村旅游满足了城市居民回归自然、返朴归真的旅游需求，日益彰显出强大的吸引力和生命力。乡村保持了完好的生态环境和文化传统，拥有优美的田园风光，村庄与自然环境构成一种和谐关系和有机整体，对乡村景观的向往逐渐成为城市居民逃离现实生活，放松身心压力，体验农家乐趣的主要心理动因。原乡规划要求在乡村旅游开发过程中有效利用乡村原生景观，严格保护有价值的景观景点，并通过合理的人工修复来完善乡村景观系统，形成真实的乡村景观意象。

    因此，在原乡规划理论指导下的乡村旅游景观规划应尽量遵循村庄现有布局，在村庄聚落的内部分区之上合理规划布局项目，并保护村庄建筑特色，不去破坏、异化现有建筑景观，这是乡村景观能够保持地方性特色，继承和发扬乡村文化传统的必然要求，也是乡村景观规划能够切实保护乡村遗产的关键。

    同时，还要保护好以乡村文化为主体的人文生态。其中乡村文化包括乡村物质文化、乡村制度文化和乡村精神文化，它是乡村景观文化内核的主要构成部分。乡村人文生态是在乡村居民建筑村落和田园景观背景下，所形成的乡村生活方式、生产方式与民俗文化的和谐的乡村环境系统。它们是乡村景观的独有表达方式，乡村旅游规划应彰显这些元素。

    总之，乡村景观规划的精髓是“原乡”，即通过景观设计、风貌控制与建筑保护，维护乡村地区的原乡风味，并在此基础上整治优化社区环境，营造良好的生活、生产和旅游氛围。乡村景观规划的根本要求是可持续性，应始终关注“人一景一地”的和谐。

    St Moritz, the showiest of Switzerland's Alpine resorts (旅游胜地), is no ordinary ski town. It's responsible for winter tourism as we know it today. It was a small band of English holidaymakers that changed Switzerland forever. In 1864 a bet took place between hotelier Johannes Badrutt and the vacationers on a damp September evening in St Moritz. As they sat around the fire at the Engadiner Kulm Hotel, concerned about returning to the foggy London winter, the Swiss manager saw a golden opportunity.

    “You holiday here in summer,” he challenged them over a bottle of red wine. “Why not enjoy the mountains year-round? Winter is so pleasant that on fine days you can even walk without a jacket.” Attracted by the promise of clean skies against a backdrop of towering peaks, the Englishmen were pleased to accept it; up until then, St Moritz had been a modest hiking destination in July and August. But if Badrutt's promise proved false, the hotelier would pay for their journey and winter-long stay. How could they lose?

    Come mid-December, the group of men returned to Switzerland. Towards the end of their week-long journey, sitting on a horse-pulled sledge and wrapped head-to-toe in furs, they went through the 2,284m Julier Pass in southeastern Switzerland. But by the time of their arrival in St Moritz, the skies had cleared, they were sweating abundantly, and Badrutt, jacketless and with his shirt sleeves rolled up, was there to greet them.

    Of course, Badrutt won the bet. Word quickly spread throughout Britain about St Moritz's distinctive climate—dry and sunny with a high degree of snow certainty. Year-round tourism landed the Alpine town of St Moritz.

    That Badrutt almost single-handedly marketed this undeveloped winter wonderland is a little unbelievable. The first tourist office in Switzerland had been established in the same year as the bet. Other resorts like the ones in Davos and Grindelwald were also popping up then. The story of St Moritz is, in some ways, also a tale of social transformation. But what Badrutt did made the Swiss mountains accessible in a way that no one else had done before, so his role as pioneer cannot be downplayed.
