Ecological tourism in wetland nature reserve along the river

The value of wetland is that it has the function of flow regulation, replenishing groundwater and conserving water, preventing the deposition of nutrients, regulating climate, maintaining ecological balance, and having high landscape value and practical value。

Zhaodong Provincial Nature Reserve is located in the hinterland of Songnen Plain, the north bank of Songhua River in the four townships of Xibali, Sizhan, Luozhou and Dongfa, with a total length of 68 kilometers and a total area of 3.330,000 square hectares, wetland area of 2.730,000 hectares, of which water area 1.330,000 hectares。It is a nature reserve with wetland and water ecosystem formed by aquatic and terrestrial organisms and their ecological environment as the main protection objects。There are 744 species of wild plants in 70 families, 214 genera, and 270 species of vertebrates in 6 classes, 32 orders, 60 families, 154 genera。There are 67 species of rare and endangered protected organisms, including 5 species of protected plants, 3 species of national protected plants and 2 species of provincial protected plants;Among them, 62 species of protected animals, 31 species of state-level protected animals, all of which are birds, of which 3 species of first-class protected birds, 28 species of second-class protected birds, 31 species of key protected animals in Heilongjiang Province。There are 36 types of ecosystem in the protected area, including shrubland, meadow, marsh and aquatic ecosystem。The protected area has extremely rich plant resources and complex and diverse ecosystem, which is a relatively complete field in Songnen Plain and has high protection value。

July is a colorful season。In this heat wave, passionate burning season, we came to Zhaodong's representative natural large-scale water surface - Kutangmu。

Around a huge nature reserve sign, a wisp of light wind with the unique taste of water town blows against the face, making people slightly drunk。Endless green, magical water shadow encircled everything, deep blue sky, white clouds, beneath the vast sparkling light, from time to time there are birds empty, osprey singing。Here, far away from the city, far away from noise, far away from pollution, there are only frogs, birds, fish leap, butterfly dance, flowers, and the sky and water。The pleasant sunshine quietly shines on the flowers, the grass, the trees，Fire in the water like red carp, stirred up a group of silver silver silver carp，And brown, brown, unknown fish of all kinds，He was swimming happily，Everything was so natural and harmonious，Makes you want to roll around on the grass，And then get some sleep，Enjoy the unique sun bath here。

On one of the shallows, there was a large area of wild thin grass, and near the stem there seemed to be a small butterfly, green and brown in color。Look carefully!It has an axillary head, consisting of 3 to 5 long ovate spikelets。It can be seen on the shallow water trestle and water shirt beside the pool。Water hair is often mistaken for salt grass, both are sedge plants, appearance is very similar, they can grow in paddy field or swamp plants, are leaf;The water hair flower beside the pool is often a place where frogs and birds hide, and it is one of the protected species of wetlands。They're not perfectly colored, but they're pretty。  In the big grassy areas of the reserve, after a bird's nest, pick up some colorful and gorgeous bird hair, a cluster of wild soybeans will inadvertently pull your pants corners, they are enchanting climbing, everywhere。According to the data, China is the country with the most preserved wild soybean resources in the world, which are widely distributed, many types and rich in resources。China attaches great importance to the collection, identification and utilization of wild soybean resources。At present, the National Gene Bank has collected and preserved more than 6,500 wild soybean resources, accounting for more than 90% of the world's wild soybean collections。

Wild soybeans are annual herbs with thin stems, strong branching and winding。The leaves are pinnately compound, the leaflets are mostly oval, but also oval, lanceolate or linear, and the flowers are purple, but very few are white。It's a high-protein plant。It provides high quality information such as entanglement, small grain, easy to fry pod and so on during the evolution of cultivated soybean。The average protein content of cultivated soybean in China is about 40%, while the average protein content of wild soybean is 45.4%, 5 percentage points higher than cultivated soybeans。The maximum protein content of wild soybean is 55.4%, which means that half the weight of the seed is protein, which is a rare fine germplasm。

In addition, it has high scientific research value, scientists are trying to cross wild soybeans with cultivated soybeans to improve the disease resistance of soybeans。

As you wander barefoot in the shallows outside the pond, the water flows through your feet to another hollow, and playful tadpoles skim over your feet。Dense water grass like a girl's flowing long hair, but also like a soft carpet, spread to the distant end。The water birds playing in the distant shoals are leisurely, carefully combing their feathers, walking elegantly, pecking gracefully, calling at different levels, and even paying great attention to the beauty of their posture when taking a nap。A line of V-shaped geese flew silently from the blue sky to the depths of the wetland。The ducks form a straight line at dusk, making ripples on the water and slowly swimming toward their nests。It is a paradise for birds and a paradise for aquatic plants。

When the rumbling speedboat, dragging several long waves, sailed into the deep water area of the pond, the endless charm of nature was obvious, the open and green water reflected the blue sky, and occasionally a line of ducks hurriedly and curiously swam out from the grass, and saw the speedboat immediately alert to dive underwater。The fish in the water were scrambling to jump，The silver scales are reflected in the sunlight，glitter，The beautiful figure draws an arc，Fell over the waves pulled by the speedboat，I wonder if the water here is too quiet，No visitors)，A huge carp jumped onto the deck of a yacht，Looking at the fish alive and dancing，I think I understand why the carp jumped the dragon gate。With the eyes of the fish falling into the water, they are attracted by the vast expanse of rushed grass in the distance. In the far distance, the green sky must be the large reed pond that they have just visited. On the edge of the reed pond, there are small black dots swimming in the long distance。The helmsman will tell you it's a clam fisherman from the neighborhood。It is!When you enjoy the scenery deep in the wetland with a different mood, you will fall in love with every spray, every grass, and everything here...

There used to be a saying here: "Beat the roe deer with the rod, scoop the fish with the ladle, and the pheasant fly into the rice pot.。It can be seen that at that time, people got along with the natural environment is how harmonious, however, all this seems to have become history, but also become human regret。

With the national attention to wetland protection, in recent years, the biological species and plant species of Zhaodong wetland are increasing year by year。The development of wetlands shows a good momentum。

Don't disturb them, nature is our good friend and the resource we depend on for survival。Let's slowly restore the history of wetlands, and let each of us do something for it!
