Abstract

According to the Inner Mongolia reached Dalai Lake Mongolia original antelope born throughout select the study results, select a land cover type, vegetation cover, slope, water, roads, settlements, grazing point seven habitat factors as the impact of Mongolian raw antelope raw habitat suitable degree of the major factors single factor of the establishment of the Mongolian gazelle habitat suitability evaluation system habitat evaluation criteria. Use of the Mongolian gazelle distribution, vegetation type survey data, the query cursor law establish of Inner Mongolia Dalaihu remote sensing image supervised classification template to complete the supervised classification, vegetation type map for the area and normalized index (Normal Differential Vegetation Index NDVI ) as a measure of vegetation cover Fig. After the build in Inner Mongolia reached Dalai Lake Mongolia original antelope born environment suitable for Evaluating the database, the use of the Arc the MAP software's space analysis (Spatial Analysis) module, the use of fuzzy assignment demand product method Dalai Lake Mongolia original antelope born environment suitable degree conduct evaluation obtained exclude anthropogenic interference with the role of potential habitat and to consider anthropogenic interference with the role of the actual habitat of the Mongolian gazelle habitat suitability maps. Mongolian gazelle, Dalaihu habitat suitability evaluation based on region Dalaihu Barag the the steppe Mongolian gazelle protection zone using FRAGSTATS3.3 software landscape pattern analysis. Compare up to Dalai Lake Mongolia original antelope actual raw environment with potential students throughout the habitat suitability evaluation results, as well as Baltic tiger steppe Mongolian gazelle protection district landscape pattern index changes, to study the of human interference role of Mongolian original antelope born throughout its conclusions are as follows: 1 Dalai Lake region in Mongolia original antelope potential students throughout suitable raw environment and moderate suitable habitat area of ??the total area of ??44.0% unsuitable habitat area accounted for 39.1%; while the actual students throughout the suitable raw environment and moderate suitable habitat area 31.9% of the total area, accounting for 55.5% of the area of ??unsuitable habitat. In Dalaihu Mongolian gazelle habitat under the influence of human disturbance, suitable habitat, moderate suitable habitat, generally suitable habitat area a decrease of 25.0%, an increase of 41.7% area of ??unsuitable habitat. Dalai Lake Mongolia original antelope actual raw territory of suitable habitat area 412885.8ha potential habitat suitable for students throughout the area 572616.6ha actual raw habitat and potential habitat compared, suitable habitat area loss of 27.9%; Dalai Lake Mongolia original antelope actual raw throughout the middle degree of suitable habitat area 546094.0ha potential habitats moderate suitable habitat area 751134.2ha actual raw habitat and potential habitat, moderate suitable habitat area loss of 27.3%; Dalai Lake Mongolia original antelope actual students throughout the unsuitable habitat area 1666504.7ha potential habitat area of ??unsuitable habitat 1176006.2ha, actual habitat potential habitat unsuitable habitat area increased by 41.7%. 2 the role of human disturbance, of Barag the prairie Huangyang protection area Mongolian gazelle reduce to suitable habitat fragmentation intensifies and spatial heterogeneity. Actual students throughout the suitability of habitat, moderate suitable habitat is generally suitable habitat average plaque area are less than the potential habitat, while the actual students throughout the unfit students throughout the average plaque area greater than the potential habitat, which show that human disturbance suitable habitat, moderate suitable habitat, the general average plaque area of ??suitable habitat to reduce fragmentation exacerbate plaque, while the average plaque area of ??unsuitable habitat increases, gathered into large plaques. The actual habitat suitable habitat, moderate number of suitable habitat patches and patch density is higher than the potential habitat, which shows that the role of human disturbance, suitable habitat, increase in the number of moderate number of suitable habitat patches and unit area of ??plaque plaque fragmentation intensified. Actual students throughout the suitable raw environment, moderate suitable habitat, generally suitable for students throughout unsuitable habitats average perimeter to area ratio are greater than the potential habitat, which show that human disturbance, four suitable grade raw environment has different degrees of crushing of moderate suitable habitat change unsuitable habitat changes. Actual students throughout the suitable raw environment, moderate suitable habitat, is generally suitable habitat average plaque shape index are less than potential habitat, while the actual students throughout the unfit students throughout the average plaque shape index is greater than potential habitat, which shows that in the human interference role under, suitable habitat, moderate suitable habitat, generally suitable habitat patch shape becomes simple, single microhabitat conditions change. Actual students throughout the moderate suitable raw environment generally suitable habitat connectivity index were lower than the potential habitat, and suitable for students throughout, not suitable for students throughout the connectivity index are higher than the potential habitat that human disturbance, moderate suitable for students throughout generally reduced connectivity between suitable habitat patches suitable habitat connectivity increase. Increased connectivity of suitable habitat, the decrease in suitable habitat area and other landscape indices lower case, does not mean that the the Mongolian gazelle habitat quality has improved.
