【砥砺奋进的5年】守护雪域绿色净土

2017-09-20 06:36:57   中国经济网

近年来,西藏自治区不断加大保护候鸟栖息地的力度。目前,全区共有各级各类自然保护区47个,建立各类生态功能保护区22个。

8月22日,记者站在拉萨河畔,清风徐来,浮光跃金。据拉萨市水利局副局长滕宝亭介绍,每年的11月至来年3月初是拉萨河的枯水期,这个时段的河床大部分裸露。为优化人居环境,拉萨市委、市政府将拉萨河城区段综合整治工程提上日程。2014年10月,3号拦河闸坝成功蓄水,首次采用了拦河闸与治导工程结合、拦河闸与桥梁结合形式,同时满足河道整治、景观蓄水和河道两岸交通连接等综合要求,现在河道中心线回水长度为2380米,平均水深2.5米,形成水域面积1395亩。3号闸蓄水后,在枯水期或平水期,拉萨河段会形成较大的水面,不仅有利于完善城市防洪体系、改善城市环境条件、提升城市品位、大量补充拉萨地下水,而且还具有巨大的生态效益和社会效益。

美丽生态助增收

在林芝市鲁朗镇罗布村,记者见到了39岁的乔卓玛。她从2012年开始经营家庭旅馆,刚开始有5间房12张床,2016年已有22张床,收入达到15万元。“政府在木板、砖瓦、水泥方面给我很大帮助,现在还有‘美丽庭院’项目,我的干劲更足了!”乔卓玛说。

据林芝市副市长张耕耘介绍,生态旅游已成为林芝市的战略性支柱产业。2016年全市已有538家家庭旅馆,生态旅游业农牧民直接参与人数达到8000人。

“电站没建之前,植被覆盖率低,地皮裸露,一遇到大风天气,沙尘漫天。桑日电站采用牧光互补的形式,既有防沙固沙的作用,也能有效改善雅江两岸的自然环境,还为当地群众提供了较多的就业岗位,增加了收入。”国家电投山南电力有限公司副总经理马天银说。近年来,山南市致力于建设以光伏、水电等为主的藏中清洁能源基地。目前仅山南市就已建成光伏电站7座,总装机为9万千瓦。

拉日铁路沿线,一片片沙丘被分成一个个小格子,每个格子都用草或者石头围起来。这就是“草方格”治流沙的办法。在铁路经过的白朗县境内,一片经过治理的沙地已被辟为万亩枸杞生态观光产业园。

“这个项目不仅发展了当地的种植业,改善了生态环境,还可以带动村民增收致富。”白朗县委书记陈昊说,该产业园雇佣附近村民参与枸杞种植,每月工资可达4000元。在产业园工人的精心管护下,枸杞树的存活率达到了八成。“枸杞树的寿命大概100年,长期培植有助于土壤下层稳固和质地改变,使沙地彻底绿化。”枸杞生态观光产业园执行董事曾令静说。

西藏自治区环保厅厅长罗杰表示,在久久为功、持之以恒的努力下,西藏高原各类生态系统结构整体稳定,生态质量良好。全区森林、草场、湿地、冰川、雪山和野生动物都得到了有效保护,大部分区域仍处于原生状态,目前自治区级生态县达7个,生态乡镇128个,生态村达到1296个,农牧民环保意识持续增强,生态脱贫稳步推进。(经济日报·中国经济网记者 崔国强 代 玲)
