Using GIS software ARCVIEW, 7 landscape indices (Diversity, Evenness, Dominance, Fractal dimension, FN, FS and Isolation ) were chosen to study the spatial patterns of the land use and soil erosion in Bishan County.
Using GIS software ARCVIEW3.3 landscape indices (Diversity Evenness DominanceFractal dimension and Isolation et.) were chosen to study the spatial patterns of the land useand soil erosion in Meihekou City.
The information Tupu of space pattern and evolutionary process were analyzed in detail taking time interval from 1987 to2001 as an example.
Choosing Pinus sglvestris Var. mongolica forest distributing area in Honghuaerji of east Inner Mongolia as research object, using GIS software such as Arcview3.2 / ArcGis8.12 and landscape pattern analysis software Fragstats3.3. This article, that get going from vegetation distributing influence issue of earth environment and human being activity which is hotspot of plant ecology and plant geography, has studied landscape space pattern and change of Pinus sglvestris Var. mongolica forest in Honghuaerji.
By using three-period aerial photo as basic information resource and withthe support of ARC/INFO , a space information storehouse is built up. Through selecting patches size , fractal dimension, dominance, diversity index, evenness index, etc,the dynamic development of land sight space pattern of Nihegou Valley in the loessplateau gully area is analysized.
The result from 1987～1995 shows that Nihegou's landsight space pattern changes significantly with the diversity and evenness index being onthe rise. The pattern shows a varied development tendency of agriculutre, fruit,forestry and animal husbandry, i. e. the obvious results obtained from integrated control .
However soil moisture in grassland after rainfall could be expressed by exponential and spherical model, and the spatial correlation coefficient, range and fractal dimension were 0.62 and 0.98, 181.80 m and 4.55 m, 1.91 and 1.99 at 0～20 cm and 20～40 cm soil layers, respectively, having the larger difference of spatial variability between two layers. Kriging maps expressed the spatial structure characters in detail.
It is widely acknowledged that it is a basic subject in remote sensing applications. Image information with different scale displays distinct spatial structure, so image analysis with single scale could not meet the heterogeneity and dynamic of pattern and process.
tabulaeformis forests with a clumped spatial pattern but rarely appeared in other forest types, indicating that P.
Based on the sampling data, a correct approach to the boundary effect on aggregation index was put forward to the spatial pattern analysis of the broad-leaved Korean pine forest in its different stages of development.
The spatial pattern of the broad-leaved Korean pine forest changing from clumped to random distribution is influenced by biological characteristic, the adaptive strategy of tree species and the natural disturbance in its entire development.
Spatial pattern analysis on individual trees in different age-classes of Larix principis-rupprechtii was made in this paper.
The spatial pattern analysis of population and community is important to understand community structure and has become one key topic in modern plant ecology.
Here, we suggest a method for adjusting boundary effect in the analysis of spatial patterns at different stages of development of the broad-leaved Korean pine forest.
In order to explain the spatial patterns of interception, we adopted grid-sampling method to install rain-gauges to measure throughfall.
Many studies have demonstrated the changes in the spatial patterns of plant and animal communities with respect to habitat fragmentation.
The DRT was found to be an effective approach to the anisotropy analysis of spatial patterns of plant populations.
Comparison of the genetic variation surveyed by starch gel electrophoresis to allozyme polymorphism indicated that morphological diversity is a good metric for quantifying spatial patterns of biodiversity.
