Arid desert region flood plain tamarix chinensis recovery method

Abstract

The invention relates to an arid desert region flood plain tamarix chinensis recovery method. According to the method, at a flood plain which is provided with or close to a tamarix chinensis seed production stand, a flood overflowing area is selected as a tamarix chinensis renewed place. Through the utilization of the characteristic of synchrony of tamarix chinensis seed maturation and flood, conventional flood plain tamarix chinensis renewed recovery or auxiliary manual seed sowing is carried out, a simple flood-control dam is set up next year in the direction of a river channel, the flood-control dam is used for stopping flood out of the seedling renewing area the flood plain tamarix chinensis, so that the tamarix chinensis seedlings can not be washed and soaked by the flood, the seedlings grow normally, a large area of tamarix chinensis community is recovered, and river banks are protected. The method also is suitable for vegetation restoration and reconstruction, ecological environment improvement, desertification prevention and control and other aspects which are carried out taking the tamarix chinensis as constructive species on flood plains which have or are close to a tamarix chinensis seed production stand. The result of a test in the Hotan prefecture shows that through the method, the tamarix chinensis can be recovered up to 2.4-2.6 plants per square meter, and compared with other methods, the rate of increase is 180-210%.

Description

technical field [0001] The invention relates to a method for restoring Tamarix tamarisk on floodplains in arid desert areas of Xinjiang, in particular to a method for restoring Tamarix tamarisks by building flood dams by using seasonal floods, bare land on floodplains in flooded areas, natural seed fall of tamarisks. Background technique [0002] Tamarix spp. L., also known as Tamarix spp. L., belongs to Tamarix family. Tamarix ramosissima, Tamarix hispida and Tamafx Leptostachys are the main species of tamarix distributed in the Hotan River Basin. River beach tamarisks are mainly distributed in floodplains and terraces of various branch channels. In the case of water shortage, many associated species disappeared, a large number of Tamarix withered, and the community declined. Tamarix sandy land is mainly distributed in the outer edge of the oasis and around the river, which can block the wind and sand, and fix the sand dunes, forming a "red willow bag". Tamarix is ​​an i...

Problems solved by technology

In inland river basins in arid regions, the occurrence and development of desert riparian tamarisk forests are closely related to changes in river flooding and river channel changes. In the past 10 years, my country has made great progress in the research on flood and riparian vegetation. However, most of these studies are preliminary studies on the impact of flooding on plant community distribution, community structure, species diversity, and soil seed bank, and rarely involve the analysis of the impact of flooding on seedling regeneration of riparian Tamarix forests.
