据报道:云南今年遭遇50年一遇的特大旱灾,楚雄20余万农村人口缺水、保山大部连续120天没有雨水、玉溪小春农作物绝收34.1万亩,昆明、曲靖、香格里拉等地近日连续发生山火.
时至今日相关问题不断出现,引起社会各方高度关注.每天的新闻的专题栏目的报道,不断解读相关产业链的损失.
至此或许我们还没有重同情受灾者的情绪中走出来,但是我要说的是,旱情的发生,作为人类的我们有着不可推卸的责任.
众所周知谁是生态系统中声明必需元素得以不断运动的介质,没有水循环就没有生物地化循环.水也是地质侵蚀的动因,一个地方的侵蚀,另一个地方的沉积,都要通过水循环.因此一旦水循环的终止,将意味着本身就比较脆弱的与水相关系最为密切的农业产业必将遭受沉重打击.因为人类的活动,改变了局域的水源,森林砍伐、农业活动、湿地开发、河流改道、建坝等等活动都可以严重改变水资源的分布格局.
虽然在这场灾难中,受害最为严重的是农民.但是在此之前长达几十年的过程中,赚取无数钱财的木材经营加工企业或个人获利无数.但如今为木材产业买单的是最为脆弱的群体.要是没有政府的相关救济行动,后果不堪设想.曾经以破坏生态系统获利的人如今却每天喝着矿泉水,开着汽车招摇过市.
从全球生态系统来看,云南地处低纬度高原,地理位置特殊,地形地貌复杂,所以气候也很复杂.主要受南孟加拉高压气流影响形成的高原季风气候,全省大部分地区冬暖夏凉,四季如春的气候特征.全省气候类型丰富多样,有北热带、南亚热带、中亚热带、北亚热带、南温带、中温带和高原气候区共7个气候类型.降水充沛,干湿分明,分布不均.全省大部分地区年降水量在1100毫米,但由于冬夏两季受不同大气环流的控制和影响,降水量在季节上和地域上的分配是极不均匀的.降水量最多是6~9月份四个月,约占全年降水量的60%.11月至次年4月的冬春季节为旱季,降水量只占全年的10%~20%,甚至更少.不仅如此,在小范围内,由于海拔高度的变化,降水的分布也不均匀.
11月至次年4月的冬春季节本来就是干旱的季节,再加上森林生态系统的破坏,干季将显得更干,雨季将显得更涝.从植物学中我们很清楚的知道,植物的生长和供水是通过蒸腾作用提供源动力的.在植物的需水量中只有1%的水被组合到植物体内,而99%的水被植物蒸腾.土壤孔隙抗重力所蓄积的水,是土壤贮水能力的上限,为植物提供可利用的水.而植物的根系的存在使得土壤保持更多的水.在干旱的季节不至于枯死,甚至为整个区域生态系统提供水分.
而如今,云南四大河流流域的生态系统历经20多年的严重破坏,贮水能力大大下降,这次的旱灾只是一个前兆.据相关林业部门不完全统计数据,自2005年以来哀牢山,无量山等重要林地遭到前所未有的破坏,加工和生产数据具体情况可看相关研究报告.政府林业部门所公布的数据时有很大水分的,因为涉及的大量问题实在非常复杂.在此也不必我多说,大家都知道的.一些相关公司的名称在此一一列举也没有多大意思.
作为一个多年以来,一直关心云南生态系统的变化的学者,非常的为云南这个以靠得天独厚生态环境相关产业链为经济支柱的事实感到无比的痛心和担忧.如今旱情所造成的损失已经突破百亿元,涉及产业包括花卉、茶叶、旅游、蜂蜜、油菜等等各种产业.在此我想大声呼吁,政府和相关社会利益团体,要从大局着想,立即行动.逐渐停止对云南森林资源的掠夺性开发,加大力度保护水源.只有生态系统的稳定才能保证经济!
According to reports: Yunnan experienced this year, once in the big 50-year drought, more than 20 million rural water Chuxiong, Baoshan most consecutive 120 days without rain, 34.1 million mu of crops crops Koharu Yuxi, Kunming, Qujing, a recent succession of Shangri-La, etc. fire.
Today, issues related to emerging, attracted all attention. Daily news reports of the thematic sections, and constantly interpret the loss of related industrial chain.
Thus perhaps we have not sympathy for the victims of emotional weight to get out, but I must say that the incidence of drought, as human beings we have a bounden duty.
As we all know who is the essential element of the ecosystem in a statement to the media in constant motion, not the water cycle there is no biological way of cycling. Water is also the motivation of geological erosion, erosion of a place, another place of deposit, must be through the water cycle. Terminated once the water cycle, will mean itself more vulnerable and the most closely related to water system will hit hard agriculture industry. Because human activities change the local water resources, deforestation, agricultural activities, wetland development, river diversions, dams and so activities can seriously change the distribution pattern of water resources.
Although this disaster, the worst affected farmers. But before the process for decades to earn money many timber processing enterprises and numerous personal profit. But now pay for the timber industry is most vulnerable groups. If no government relief operations related to the consequences. Have to destroy the ecosystem of people now have a daily profit of drinking mineral water, driving cars through the streets.
From the global ecological systems, the Yunnan Province is located in low latitude plateau, location specific, complex terrain, climate is also very complicated. The main impact of high pressure formed by the Nanmengjiala plateau monsoon climate, the province's most Dongnuanxialiang, year-round spring climate characteristics. Rich and varied weather patterns across the province to the north, tropical, subtropical, subtropical, subtropical north, south temperate zone, temperate and highland climate zone in a total of seven climate types. Abundant precipitation, dry clear, are unevenly distributed. Most parts of the province in the 1100 mm annual precipitation, but by different summer and winter atmospheric circulation control and influence,
Precipitation in the seasonal and geographical distribution is very uneven. Most precipitation is 6 to September for four months, accounting for 60% of annual precipitation. November to next April's spring and winter for the dry season, annual rainfall only 10% to 20% or less. Moreover, in a small area, due to changes in altitude, rainfall distribution was not uniform.
November to next April's spring and winter is the dry season have been, together with the destruction of forest ecosystems, the dry season would appear to be more dry, the rainy season would appear to be more floods. We know from botany to know, plant growth and transpiration of water supply is provided by the source or power. Water requirements of plants, only 1% of the water is combined into plants, while 99% of the water transpiration by plants. The accumulation of anti-gravity of soil pore water, soil water storage capacity is the maximum available for the plant to provide water. The presence of plant roots makes the soil to keep more water. Withered in the dry season Buzhi Yu,
Even for the entire regional ecosystems provide water.
Today, four major river basins in Yunnan Province ecosystems than 20 years of serious damage to water storage capacity greatly decreased, this drought is only a precursor. Incomplete the forestry sector, according to the relevant data, since 2005, Mountain, and other important forest Wuliangshan was unprecedented destruction, processing and production data to see the specific circumstances related to the study. Government data released by the forestry sector, there is great water, because a lot of issues involved is very complex. This is also not to say, we all know. The name of a number of related companies listed in this 11 have little meaning.
As a many years, been concerned about changes in the ecosystem in Yunnan scholars, this is for Yunnan to rely on unique ecological environment-related industry chain as economic pillars of the Shishi truly feel the pain and worry. Now the losses caused by drought has broken 10 billion yuan, involving industry, including flowers, tea, tourism, honey, rape, etc. all kinds of industries. I would like to speak out, the government and related social interest groups, from the overall interests, take immediate action. Forest resources in Yunnan gradually stop predatory development, greater efforts to protect water resources. Only the stability of ecosystems to ensure economic!
