Ecological attribute data set of desert vegetation in the middle and lower reaches of Heihe River (2015-2017)


This data set contains the observation data of the ecological properties of desert vegetation in the middle and lower reaches of heihe river from January 1, 2015 to July 31, 2017, including 528 pieces of data, including 262 pieces of ammodena, 81 pieces of red sand, 71 pieces of spinous thorns, 66 pieces of salt claws, 42 pieces of pearl pork hair vegetables, 4 pieces of black fruit wolfberry desert, and 2 pieces of desert of Chinese date.Ecological attributes include 4 groups of ecological parameters and a total of 15 categories of 74 indicators, as follows:

Vegetation structure parameters (25 indicators in 5 categories) :

Coverage: total coverage, three-layer coverage, average diameter of canopy;

Height: three-layer height, canopy thickness, litter thickness, moss thickness, maximum root depth;

Density: layer density and average diameter of trees;

Leaf area index: maximum leaf area index and minimum leaf area index of three layers of trees and grass;

Phenological stage: leaf spreading stage, leaf filling stage, leaf deciduous stage, complete deciduous stage.

Vegetation productivity parameters (16 indicators in 3 categories) :

Aboveground biomass: total biomass, three-layer stem biomass, leaf biomass;

Root biomass: root biomass, 0-5, 5-15, 15-30, 30-50, 50-100, 100-250cm fine root biomass;

Other biomass: litter layer, moss layer biomass and carbon storage.

Physiological and ecological parameters (24 indicators in 4 categories) :

Biomass distribution: proportion of rhizome and leaf distribution;

Element content: carbon content of roots and leaves, carbon - nitrogen ratio, carbon content of litters, carbon content of moss;

Blade shape: specific leaf area, blade length and width, leaf inclination;
