生态护坡的本质和特点
生态护坡的本质和特点
Nature and characteristics of ecological slope protection
(一)生态护坡并非与传统护坡完全对立
(1) ecological slope protection is not completely opposed to traditional slope protection.
一部分生态护坡是在传统护坡基础上发展而来,尽管国内外还没有统一的定义,但与传统护坡的区别还是明显的:
A part of ecological slope protection is developed on the basis of traditional slope protection. Although there is no unified definition at home and abroad, the difference between ecological slope protection and traditional slope protection is obvious.
生态护坡较传统护坡更具有自然生机,与周围景观相协调。生态扩坡具有一定的开放性,能保护生物的多样性,较少改变河道生物栖息环境。生态护坡材料以环保材料为主,多数为天然材料,对环境污染小。
Compared with the traditional slope protection, ecological slope protection is more natural and harmonious with the surrounding landscape. Ecological slope expansion has certain openness, can protect biodiversity, and change river habitat. Ecological slope protection materials are mainly environmentally-friendly materials. Most of them are natural materials and have little environmental pollution.
传统护坡主要指砌石护坡和目前大量使用的预制混凝土块。这些护坡中的干砌块石护坡随着时间久远和大自然的自我修复,与自然界达成新的平衡,与天然土坡一样,它上面也生长植被,也具备生态护坡的特征。随着时间的流逝,新的平衡在新的条件下重新建立,这是自然规律。只要我们认识到这点,就不会把传统护坡与生态护坡完全对立。
The traditional slope protection mainly refers to masonry slope protection and the widely used precast concrete blocks at present. With the long time and the self repair of nature, the dry masonry revetment in these slopes has reached a new balance with nature. Like natural slope, it also grows vegetation and has the characteristics of ecological slope protection. With the passage of time, the new balance is rebuilt under new conditions. This is the natural law. As long as we realize this, we will not completely oppose traditional slope protection and ecological slope protection.
(二)生态护坡不等于景观护坡,景观护坡受水位线限制
(two) ecological slope protection is not equal to landscape slope protection. Landscape slope protection is restricted by water level.
一般认为生态护坡就是植被护坡,这一观点不准确。观察水库或湖泊,可以发现其水面线与岸坡植被之间有一条明显的水平分隔带,它是由水面线涨落造成的,植被一般在水面线之上。河道边坡同样如此,植被生长受水位、季节、温度和雨量的影响,在河道边坡上呈水平分布,与护坡材料相关。但即使是天然土坡,在一定的高程之下也无法布置植被护坡,尤其是在大江大河。可以说景观护坡(植被护坡)只是生态护坡之中的一种,修建景观护坡必须首先考虑水位影响。
It is generally considered that ecological slope protection is vegetation slope protection. This view is not accurate. To observe the reservoir or lake, it can be found that there is a clear horizontal separation zone between the water surface line and the bank slope vegetation, which is caused by the rise and fall of the water surface line, and the vegetation is generally above the surface line. The same is true for river slopes. Vegetation growth is affected by water level, season, temperature and rainfall. It distributes horizontally on river slopes and is related to slope protection materials. But even natural slopes can not arrange slope protection under certain elevation, especially in large rivers. It can be said that landscape slope protection (vegetation slope protection) is only one of the ecological slope protection, the construction of landscape slope protection must first consider the impact of water level.
(三)生态护坡不是解决河道污染的有效手段,其自然净化河道的能力有限
(three) ecological slope protection is not an effective way to solve river pollution, and its natural purification capacity is limited.
人们最初设计生态护坡的目的之一是净化河道,但这一构想几乎无法实现。河流水体污染主要来自城市排污、农田化肥农药、大气酸雨,自20世纪50年代以来,发达国家都面临过水环境污染,没有哪一个国家主要依靠生态措施宋减缓或消除水污染。建没生态护坡不能夸大其白净能力,更不能寄希望它来治理污水。
One of the purposes of designing ecological slope protection initially is to purify the river course, but this idea is almost impossible to achieve. River water pollution mainly comes from urban sewage, farmland fertilizer and pesticide, and atmospheric acid rain. Since 1950s, the developed countries have faced water pollution. No one country mainly relied on the ecological measures to alleviate or eliminate water pollution. No ecological slope protection can not exaggerate its whitening capacity, nor can it be expected to treat sewage.
(四)生态护坡建设应适应我国自然条件和经济社会发展
(four) ecological slope protection construction should adapt to the natural conditions and economic and social development in China.
生态护坡是实现生态水利的一部分,因此发展生态护坡必须适应我国自然条件和经济社会发展的需要。
Ecological slope protection is a part of ecological water conservancy, so the development of ecological slope protection must meet the needs of natural conditions and economic and social development in China.
1.护坡首先要满足防洪功能,就是说护坡主要作用是防御洪水,其他功能都服务于防洪,护坡满足生态需求同样不能因此而削弱其主导功能。
1. slope protection should first meet the function of flood control, that is to say that the main function of slope protection is to defend the flood, other functions serve the flood control, and the slope protection to meet the ecological needs can not weaken its leading function.
2.生态护坡最重要的特征是恢复河流天然属性。应尽量选择天然材料,如天然石材、草皮等,尽量少用水泥和人工合成材料。天然材料产生于自然耐久性好,与河流不相排斥,即使发生化学反应也很漫长,而人工合成材料却难以做到这一点。天然材料的另一特性就是容易在河道中形成新的自然平衡,较快恢复河道天然景观。
2. the most important feature of ecological slope protection is to restore the natural attributes of rivers. Natural materials, such as natural stone and turf, should be selected as much as possible, and cement and synthetic materials should be used as little as possible. Natural materials are produced in natural durability and are not repulsive to rivers, even if chemical reactions are long, but synthetic materials are difficult to do this. Another characteristic of natural materials is that it is easy to form a new natural balance in the river course and restore the natural landscape of the river quickly.
3.发达国家修建生态护坡的一些做法值得借鉴,但要进一步消化吸收,不能照搬。
3. the practice of building ecological slope protection in developed countries is worth learning, but it should be digested and absorbed and cannot be copied.
