申遗成功是文化保护新起点

塔元培

    日前,德国波恩第三十九届世界遗产大会上为中国响起的掌声,让远在万里之外的人们欣喜。世界遗产委员会各成员一致同意,湖南永顺老司城遗址、湖北恩施唐崖土司城遗址、贵州遵义海龙屯土司遗址获准列入《世界遗产名录》。至此,中国世界遗产总数已达48项,位居全球第二。

在国人的印象中,申遗成功或许不算什么大新闻,但对于生活在我国西南山区的土家族、苗族和仡佬族同胞来说,“土司遗址”跻身世界遗产殿堂,是令人瞩目的文化事件,绵延千百年、凝聚“齐政修教、因俗而治”管理智慧的土司制度及其文化,也因此向世界揭开了神秘面纱。各美其美,美美与共,当“世界遗产”在广袤中国大地上,拥有了来自更广大区域、更众多民族的新注解,中国传承文化、保护遗产的努力,再次得到了世界肯定。

    从1985年加入《世界遗产公约》算起,中国的“申遗之路”已走过30年。与改革开放的时代潮流相伴,拥有五千年不断流的文化的中国人,在走向现代化的路上,对这片土地上的文化遗产,不断加深着认识和理解,加大着保护与传承的力度。目前,除了近50处世界遗产,我国还有国家历史文化名城125个,历史文化名镇252个、历史文化名村276个。这些数字的背后,是从中央到地方、从政府到社会为文化遗产倾注的努力,是赓续文脉、珍视文化的普遍共识。

    《世界遗产公约》第四条明确指出,文化和自然遗产的确定、保护、保存、展出和遗传后代,主要是有关国家的责任。从这个意义上说,世界遗产的名号,意味着更大的责任。申遗成功不是终点,而是履行保护责任的新起点。

    此次申遗成功的土司遗址,非常脆弱,不易保护。令人欣慰的是,得知入选的好消息,各地在喜悦的同时,也表达着对保护责任的清醒与担当。在永顺老司城,当地县委书记的第一反应是“进一步完善保护体系”,制定村规民约,对遗址区进行24小时巡查值守;在遵义海龙屯,当地政府正在谋划关口、城墙等遗存的修缮保护,聘请专家学者把脉文物安全。

    当然,如果把观察的视野打开,在越来越重视遗产保护的今天,依然存在一些现实问题。在一些地方,存在重申报轻保护、重开发轻保护等倾向,一些人把申遗作为一项政绩工程来抓,不惜投入大量人力物力,申报下来后却忽略了后续的科学保护和管理;一些地方将历史建筑改造成豪华酒店,为做大“门票经济”不顾文化遗产的承受力,心里只算经济账。凡此种种,都会对文化遗产造成伤害,造成难以弥合的裂痕。

在文化传承中,保护与开发是永恒的课题。文化遗产不可复制,也不能再造,不管是申遗还是入选之后,保护应该始终放在第一位。也只有做好保护,文化遗产才能可持续利用,更好造福于民、传之子孙。因此,算好文化账、算清社会效益账,而不是以“摇钱树”思维看待文化遗产,应该是我们面对先人文化财富的最基本立场。

    一位80多岁的美国老华侨曾感慨,少小离家的他对家乡的印象已经模糊,唯一记得的是家乡的小庙,临行前他在庙里磕头,走的时候也是一步一回头。“望得见山、看得见水、记得住乡愁”,本质上是一种文化的忧思与向往,这是全社会共同面对的课题。德国波恩世遗大会上发表了《“为遗产联合起来”波恩宣言》。而在中国,今年文化遗产日的主题是“保护成果,全民共享”。不忘本来才能开辟未来,每个人都

行动起来,少一些“到此一游”的任性,多一些敬畏文物的自觉,不断守好人类共有的文化遗产,才能让它的光芒照亮心灵。

    Changes that will help you get more done than ever before

    Win tomorrow today. All it takes is setting aside five minutes every evening before you end your work to establish the one goal you will accomplish tomorrow. Sometimes, the hardest part of getting things done is deciding which thing to work on first. If this decision making has to happen first thing in the morning, it can create a block to progress, which is no way to start your day. By giving yourself a head start the night before, you're allowing your most productive work hours-in the morning—to be used to the fullest by not having to wonder about on choose what you'll work on first.

    Having a morning routine is one of the best things you've done for yourself. It not only helps you set your day up to be successful by gaining great power first in the morning, but it also allows you to guarantee that you are going to get a set number of things done right away. This way, no matter what your day brings, you should keep in mind that your health and nutrition are the most important. Your morning routine includes a workout, drinking water, meditation(冥想), and ensuring you get the nutrients you need to perform at a high level all day.

    One of the common mistakes people make is to focus entirely on whatever task is next on their list and promise not to move or pause until it's done. Tasks will expand to the time assigned. Instead, try to be inspired from successful people and setting up timed periods for both focused work and breaks. Establishing sections where you have a set amount of focus time followed by a set amount of refresh time prevents you from being distracted(注意力不集中的)and helps you make great progress on the tasks and projects you're working on.

    Being extremely future-focused and ambitious is great, but if you're always moving from one task to another, you could be missing out on a big growth opportunity. In order to learn what's working and what's not working, you need to spend time reflecting. Set aside some time at least every 10 days to reflect on the good, the bad, and everything in between. When you can identify what's working, you'll know what to double down on. You'll also be able to identify the things that are holding you back from getting where you want to go, and to think out solutions for those struggles in order to remove them in the future.

    If you really want to get more done, you have to stop focusing on what you can't do, and start focusing on everything that's going right. Being grateful will not only increase your happiness factor, it will also make you more productive. When you have a positive attitude and take time out to recognize everything you have to be grateful for, you're able to focus on the many things you have accomplished, you're more likely to make progress and get more done.
