Reversal of Ecological Thinking

 Reversal of Ecological Thinking

CCTV broadcast a recent first time in eco-benign Horqin Sandy reversal of the message. As a member of Sand, after nine years of hard efforts, to hear this news, excitement is not quiet a long time, years of pay, until finally the return of nature. Although only a modest best, but after all, all my life. This is not what we dream it? Excitedly, and his soul can not say there is a vague concern, people feel uneasy.

worry I: Restoration does not mean the restoration of ecological systems, it does not mean the restoration of biological diversity. The first time reversal of Horqin ecological restoration is only the initial phase of ecosystem Horqin.

Not long ago, bring to the Bayan volunteers inspected the Han Shan.

Bayan Khan Mountain is located about five kilometers south Balinyouqi, elevation 1290 m, Mountains Mountain Range. According Balinyouqi is recorded: the Kangxi Emperor as achievements of its grass in, the Hui placed Temple Thus, the former Bayan Khan mountain steep mountains, dense pine forests, is a good habitat for wildlife, insects Haw Par wolf, roe roe deer, everywhere.

foot inspection, did not find any traces of large wild animals, only some rabbit droppings.

After four years of closing off the main road along the line area within a two year grazing, the area has been showing a marked improvement in ecological environment. A case of the original sand road to the phenomenon of burial is no longer there. Humilis hillside half a person of deep, if not take the path has been unable to move. The back slope of the mountain and the valley sides, the original development of secondary forest is also very good, with oak trees, birch, mountain elm, mountain Choji tree, mountain pear, apricot hill, mountain poplar, juniper,UGG boots, hickory, linden tree, and shrubs such as maple, but also scattered pine. Experienced the vicissitudes of the years looking at the baptism of the remnants of ancient pine trees, one can not but Qijing. Stop and wait a long time, imagination, the brain rapidly running, try the search had Unfortunately, no matter how hard, and always link it up.

climbed along the top of the Kangxi emperor's footsteps, despite the endless scenery along the way, there are list of small hills feeling. However, the overall feel some regret. ① large areas of virgin forest was gone, only a few remnants of pine and some broad-leaved forest. ② not seen any large wild animals and even small animals.

Restoration does not mean the restoration of ecological systems, it does not mean the restoration of biological diversity. Eco-system itself, including plants, animals, insects, microbes and even inorganic substances and so on. The first time reversal of Horqin ecological restoration is only the initial phase of ecosystem Horqin, it can be said that this is only the first step before the Long March.

worries II: forest in the access to the same time, if not timely Planting monthly, large areas of logging also may make the ecological environment has been gradually restored once again been destroyed

It is understood that Qi Xian has been around a large area of poplars were cut down, particularly for individual Qixian. Reflect the people One can imagine the situation in the region how serious deforestation. In addition, the former hunting place I have played a large area of poplars have been cut away, leaving a bare hill and dale, stumps, rushing for a white, terrible to see.

hematoxylin I live in nearly every day, pull the transport vehicle Poplar, estimated a few hundred cars a year or so can be taken away. Severe desertification in this region, the ecological environment is fragile, economic forest, while in the access, if not for Planting monthly, large areas of logging also may make the ecological environment has been gradually restored once again been destroyed.

concerns three large-scale afforestation does not mean restoration ecology, or even equal to the destruction of ecology.

afforestation in some known professional companies in the large-scale afforestation before you flatten all the grass, repair the irrigation channel, marked with deep wells. Note that their choice is relatively flat, sandy grasslands and not! In order to The length of the original vegetation has pushed levels failed to survive after planting, but to create four acres of new sand.

some companies sell a lot of Yunnan, Guizhou and other places to be cut down large tracts of forest land. And these companies also claim to give investors procedures for legally harvested, hype and so forth.

these acts,Bailey UGG boots, afforestation, or the call and took the opportunity to collect money by the Government? Restoration ecology, or ecological damage?

All of these are worthy of attention.

● does not mean resumption of large-scale afforestation and ecological, or even equal to the destruction of ecology. Three North is a warning.

concerns four, everything is the Second Law of Reversal, some plants can necessary materials sand --- microphylla shrub grass still children (small Caragana), Da Lang (Hedysarum Mongolia), Mongolian in history and the absence of the species. The grass was in the 70s introduced by Simon and conduct aerial desert areas and large area coverage.

Darling leave for a few years so the teacher said after the Saudi study: The grass is not native species. This thing is very strong vitality, developed root system, can be formed not take advantage of long grass, and gradually into the region's top-successional communities. Other grass species was inhibited, difficult to survive, is to produce a new culprit in one of the grassland desertification!

At the time, I was very puzzled by these words. The past few years has been concerned about and observe children's growth and development of Caragana state. Finally found the plant did cause both Sand and sand are consistent: Reversal of laws of that everything.

microphylla is a woody deciduous shrub children, developed root system - up to ten meters deep, in the absence of livestock grazing, height up to one high or so. The more buried in the sand, the more branches, growing more prosperous, strong fixing capacity. Microphylla sand buried a child, can form dozens to hundreds of article root root section, branch consisting of a large shrub,bailey UGG boots, up to the sand thickness of 6 to 7 meters high, crown up to 13.5 × 11.0 m 2. The grasses form a bush after the rapid expansion, from small shrubs to big bushes. In addition to tiller than root can also be propagated by seed. Around it, what things can not survive easily in the survival of planting trees and grass around it. If you want to get rid of it, then, almost impossible. Although children can

microphylla sand, but also create sand dunes. According to the principle of Bernoulli Theorem (1738, Swiss physicist Bernoulli movement of fluid pressure in the study and found in the steady flow of fluid when flowing through the narrow part of the flow rate will be faster, while the pressure decreases; through the wide part of the flow rate will be slower,UGG boots cheap, and the pressure increases. This is the Bernoulli's theorem), a shrub form a resistance area, the air flow resistance to interference by the after part of the upward flow side of the bush after the formation of negative pressure zone. Lower air velocity, dust down, gradually, a small sand dunes, and turns into a large sand dunes. As shown:

In addition, the shrub on both sides of air, due to the narrow tube effect, air flow speed, in shrub form two grooves on both sides, and keeps getting deeper. Air flow and air flow in the upstream side of the dual role under the point of the shrub-like sand dunes formed by the gradual formation of mobile dunes and the dunes, sand dunes into a ribbon. Dune formation as shown:

Thus, Caragana children, Da Lang, etc. Sand is not the best grass pioneer shrub species. In this case, how to change the status quo and how to choose the best grass seed, sand control in the years that I am in the process of planting the practical problems encountered, and also my confusion. Hope the scholars will be given FAQ, the best the best can give a realistic sand control program, and try to avoid repeating similar mistakes.

Horqin grassland can really restore hope and pray the beautiful style. Source: Protection of grassland joint project
