The upper reaches of the Xiliao River is located in the southwest of the northeast of my country、East of Inner Mongolia Autonomous Region，The transition zone belonging to the Eurasian grassland area and the broad -leaved forest area in the northeast，and North China、Northeast、Dagua and Mongolian plant areas intersect。Since the area is located in the monsoon edge area、The transition zone of the arid area and the semi -drought and semi -humid area、Edge on the Edge of Korqin Sand，Sensitive response to environmental evolution and human activities，Climate change can easily affect human activities。

In order，Discuss the situation of human -land relationship at the time，We sitting at the Weijia Wopu Site of the Typical Site of the Hongshan Cultural Period、Xinglonggou No. 2 place，Using flotation method to obtain millet including crops、Cycles and other weed carbonized plant seeds (Hekeei、、Douke、Lip -shaped Department、Eggee, etc.)，But the absolute number of the abrupt unearthed in the cash crop is very low，Solid and crickets are only 7%。Floating results Bet365 app download display，Hongshan Culture period in the upper reaches of the Xiliao River has begun to engage in agricultural production activities，And millet、黍 is the main。

After the "8200 Years of Climate Change"，The new climate enters the big warmth stage，7500-6000 years ago is the most suitable climate，There is climate fluctuations from 6000-5000 years ago。Liaoning Province Huanren County Nuanhe Cave Strangler Δ18o record has a good correspondence with solar radiation，It show，High temperature，But it reduced to a low value around 6400 years ago。After the Hongshan culture period, precipitation fluctuates changes，But it is generally weaker than the early stage (8000-7000 years ago) and later (3700-3200 years ago)。Compared to the early Xinglongwa -Zhao Baogou period and the Xiajiadian in the Bronze Age of the Xinglongwa period，The summer wind in the Hongshan Cultural period is weaker，Low precipitation。Warm、Drought but relatively stable climatic conditions may ensure the sustainable development of Hongshan culture。

Analysis based on flotation results，The early economic form of Hongshan culture of the Wei Jiawupu site includes agricultural production ingredients，and plant drought -resistant crops、黍 is the main。Su、黍 is an important crop type of drought agriculture in northern China，The bet365 best casino games primitive drought agricultural agriculture with millet in the Xiliao River Basin began in the period of Xinglongwa Culture。The first location of the Xinglonggou site has more than 10,000 of various plant seeds.，Including 黍、Music two types of cultivation cereals，The carbonized coriander unearthed in the place still retains the characteristics of a stronger wild ancestor，long granular shape，Small size，It should be the initial variety in the process of cultivation of crops。

Wei Family Wo Shop Site、Hongshan Cultural Period, represented by the second place of Xinglonggou，、The drought agricultural system represented by 黍 should be the tradition of drought agricultural tradition in the Xinglongwa culture period of Xiliao River，But the millet during this period、The absolute quantity and probability of unearthed，Far below the Central Plains Cultural District of the same period，At the same time, the lower level of the Xiajia Store in the Bronze Age is far lower than the Bronze Age。The Later of the Weijiawo Site and the second place of Xinglonggou for identification and display，Su、The absolute number of 黍 is far lower than the third place of Xinglonggou in the lower level of Xiajiadian and the site of the three stores of Songshan District (9665 grains、黍 99348)，Su、The probability of unearthed 黍 is far lower Bet365 lotto review than the latter。This description，With the Wei Family Wowu site、The Hongshan Cultural Period, represented by the second place of Xinglonggou, the agricultural system is not high in the living model.。

This difference may be caused by the diversified industry model of Hongshan Cultural period。Stone feature unearthed from Hongshan Culture shows that the stone tools related to agriculture are mainly based on large -scale cutter and stone 耜，Lack of farmland shovel tools，It may reflect the production status of large -scale reclamation and extensive cultivation at that time; thin blades and sharp stones with high probability of unearthed probability and bone stembone blade in other agricultural areas，It is mostly related to cutting skin，Reflected hunting、The existence of the breeding industry; Shi Ji that appears in many sites，It also reflects the economic form of hunting。

Animal skeleton unearthed from the cultural site of Niuhe Lianghongshan includes domestic animal animals and sika deer、狍、獐、Dog、Black Bear、Bunny、Dog、Northeast Mouse and other wild animals。Hongshan Cultural Stranging of Hongshan front site and Baiyin Changhan's bones of deer，Show hunt、Family animal breeding occupies a large proportion in economic life。

During the floating process of the Wei family nest site，At the same time, a large number of fish Bet365 lotto review bones and software animal crustaceans and some animal bones were found，Show the fishery economy occupies a large proportion in the economic life of the ancestors of the Weijiawo site。picking、Wild fruits such as walnuts and Xiaye Pu，A source of food for the early ancient ancestors of the early ancient ancestors in the Xiliao River area。The stone grinding plates and grinding rods seen in the Weijiawopu and other sites should also be collected、Processing is related。

Visible，Hunting、Home Animal breeding、Fisheries、Collection of the same position in the way of life in the Hongshan Culture period also lives an important position，、Northern China, represented by crops, is not high in agriculture in the northern China。Due to the rich landform species in the upper reaches of the Xiliao River，Significant altitude differences (120-2100 meters)，Different landform units provide environmental conditions for the diversification of human production methods in the region，Promoting the diversification of the living industry in the region。

Hongshan culture lasts longer，Overall，Whether it is an unearthed relics，Still the scale of the settlement is higher than other periods，This may be the product of the "gathering effect" at the time scale。Dan's number of sites and sites in the Chifeng area of ​​the Red Mountain Culture period bet365 best casino games is still lower than the later cultural period of Xiajiadian and the upper cultural period of Xiajiadian。At the same time，During this period, humans tend to live in Glita、Low -altitude areas such as the foundation plain and the Hongji Plain，and high altitude areas such as hills and low mountains，The former may be affected by the fishery economy，The latter may be related to hunting and collecting economy。

Hongshan Cultural Period in the upper reaches of the Xiliao River engaged in agricultural production activities，And millet、黍 is the main，Hunting at the same time、Home Animal breeding、Fisheries、Collection also occupies an important position。The reason for it，The relatively dry climate conditions during the Hongshan Culture period of the West Liao River may limit the development of the agricultural economy in the region，The ancestors have to engage in hunting、Home Animal breeding、Fisheries、Collection, etc. to supplement food resources。Different landform environmental characteristics may also promote the diversification of the living model。
