Spatial pattern and spatial association are important methods to study population diffusion and community succession.Melica przewalskyi is a kind of perennial rhizomatous clonal herbs with strange taste,which is not edible for grazing animals.With the infuluence of climate change and overgrazing,Melica przewalskyi gradually replaced Stipa Krylovii and became a single dominant specie in the northern slope of Qilian Mountains.It is very important to understand their distribution patterns and… Expand

Rapid Expansion of Melica przewalskyi Causes Soil Moisture Deficit and Vegetation Degradation in Subalpine Meadows
Invasive noxious plants have important impacts on community dynamics and ecosystem functions in grasslands. Since the 1960s, the noxious plant Melica przewalskyi has spread rapidly and formedExpand
Fine-Scale Distribution Patterns of Phragmites australis Populations Across an Environmental Gradient in the Salt Marsh Wetland of Dunhuang, China
The spatial distribution pattern of plants often reflects their ecological adaptation strategy and is formed by their long-term interaction with environmental factors. In this paper, the clonalExpand


Fine-scale spatial distribution and spatial association of Stellera chamaejasme population
The spatial association between plants will turn from positive to negative if their size differences are enlarged increasing, with the growth of population, the spatial association gradually transferred to non-significant, then spatial association tended to complex at more bigger scale. Expand
Rehabilitation Process of Degraded Melica Przewalskyi Grassland in the Upper Reaches of Shiyang River
The processes of vegetation rehabilitation were studied through applying special herbicide to control Melica przewalskyi Roshev and reducing grazing pressure in Qilian mountain.The results showedExpand
Fine-scale spatial pattern of Artemisia frigida population under different grazing intensities
The relative strength of the various ecological processes that drive community composition would change as grazing intensity increases, and grazing would be replaced by interspecific competition as the dominant process determining species abundance and distribution. Expand
Spatial pattern analysis of individuals in different age-classes of Larix principis-rupprechtii in Luya mountain reserve, Shanxi, China
The technique of point pattern analysis is effective and easy to use method in species pattern study and suggests that the inner-relation of Larix principis-rupprechtii population in Luya reserve is rational, which can increase the population ability of anti-disturbance and competition, and increase the stability of forest community.

Fine-scale spatial patterns of Stellera chamaejasme population in degraded alpine grassland in upper reaches of Heihe,China
The point pattern method was used to analyze population pattern, size and density of S.chamaejasme cover in the upper reaches of Heihe,China, and found that with increasing cover, the population density and territory density tended to increase,decrease, and then increase and the number of the S. chamaejame population tended to increased and decrease in turn.

Spatial pattern analysis of a Rhododendron-Abies virginal forest near timberline on the eastern edge of Qinghai-Tibetan Plateau,China
It was inferred that adaptation of the two species to the habitat of alpine timberline and spatial segregation of patches between the twospecies contribute to the coexistence of A.faxoniana and R.agglutinatum. Expand
Spatial patterns of Castanopsis eyrei and Schima superba in mid-subtropical broad-leaved evergreen forest in Gutianshan National Reserve,China
Analysis of the main mechanisms of distribution pattern of Castanopsis eyrei and Schima superba in GTS (Gutianshan) forest plot suggested that dominant species facilitated coexistence of other species through emptying space for colonization of otherspecies. Expand

Spatial pattern and process in forest stands within the Virginia piedmont
Abstract Question: Underlying ecological processes have often been inferred from the analysis of spatial patterns in ecosystems. Using an individual-based model, we evaluate whether basic assumptionsExpand
