Method for artificially promoting populus euphratica forest to recover into forest by simulating populus euphratica flood habitat

Abstract

The invention discloses a method for artificially promoting a populus euphratica forest to recover into a forest by simulating a populus euphratica floodplain habitat, and belongs to the technical field of populus euphratica forest recovery into the forest. By means of the method, according to the ideas of depending on nature and recovering the nature, in abandoned cultivated land, returned cultivated land and other areas with populus euphratica distribution and few populus euphratica seeding, less water resources are used for simulating the floodplain habitat of populus euphratica seed germination; the seeding amount is increased through manual reseeding, the germination number of populus euphratica seeds in the areas can be remarkably increased, and then the seedling distribution numberand uniformity are improved; and populus euphratica habitat conditions are guaranteed through manual management measures in the later period, populus euphratica seedling young forests grow up as soonas possible, and the natural recovery number of the populus euphratica in the areas is effectively improved. By means of the method, the natural recovery capacity of the populus euphratica in the abandoned cultivated land and the returned cultivated land can be effectively improved, and the method is suitable for recovering the populus euphratica into the forest in arid desert areas, especially abandoned cultivated land and returned cultivated land seedling regeneration young forest areas.

Description

technical field [0001] The invention relates to the technical field of Populus euphratica forest restoration, more specifically, to a method for artificially promoting the restoration of Populus euphratica forest by simulating the floodplain habitat of the Populus euphratica River. Background technique [0002] Populus euphratica is a species of Populus in the family Salicaceae. It has important functions such as producing organic matter, conserving water, maintaining biodiversity, and regulating climate. It plays an important role in inhibiting the expansion of desertification and maintaining ecological balance. The middle reaches of the Tarim River, the longest inland river in my country, and the section from Yingbaza to Kaerquga, is the area with the most concentrated distribution of primitive Populus euphratica forests and the most complete preservation of the Populus euphratica desert ecosystem in my country and even in the world. This area is mainly dominated by Populu...

AI Technical Summary

Problems solved by technology

Excessive use of water resources has resulted in a continuous decline in groundwater levels, which has exacerbated the aridity of desert vegetation, resulting in large-scale decline of natural Populus euphratica forests, withered shoots, weak fruit and even death

[0004] In 2000, the first emergency water transfer of the Tarim River was carried out, which was later changed to a permanent water transfer. Over the past 20 years, an average of 405 million cubic meters of ecological water has been discharged every year. In 2016, the "Save Populus euphratica" operation was carried out around the main stream of the Tarim River and the Yarkand River, Aksu River, and Hotan River. The distribution of Populus euphratica forests on both sides of the four major tributaries of the Tahe River, Kaidu-Kongque River, etc. has been expanded. After the implementation of the project, especially after the management of water resources has been strengthened, the abandoned and converted farmland along the Tahe River has continued to increase. However, due to human activities, The distribution of natural Populus euphratica trees in this area is less, the amount of natural seed fall is insufficient, and the natural regeneration and recovery of Populus euphratica is slow. How to make the original abandoned farmland and converted farmland become forests as soon as possible and increase the area of ​​Populus euphratica forest is an urgent problem to be solved
