Suitability Analysis Based On3S Technology Of Nesting Habitat Of Red-crowned Crane In Zhalong National Reserve

Habitat suitability analysis for species protection and nature reserve management plan has very important significance. Red-crowned Crane is protected birds, endangered species at the national level, Zhalong National Nature Reserve is important in our red-crowned crane breeding grounds, a clear distribution of its suitable habitat is critical to protect the red-crowned crane. This study was conducted from2012to2013between May3to collect the nest-sites on field distribution of data points, and microhabitat use in2013Zhalong Landsat-8TM remote sensing images to extract environment variables, combined with DEM elevation data, human disturbance data model be crowned crane in MAXENT nesting habitat distribution predicted output in ArcGIS reclassified get Zhalong suitable nesting habitat distribution method based on expert experience. This paper compares the2004and2013habitat quality, quantitative analysis of the changes of the past10years in protected areas Zhalong crowned crane suitable nesting habitat. The main results obtained are as follows:A model through the ROC curve test, the test results show that the training set, validation set AUC values were0.901,0.935, both excellent level. TSS test is0.775, reached a good level.2Jackknife test results showed that:the green vegetation index, soil moisture index, distance from the road is the main factor affecting the distribution of red-crowned crane, elevation, slope, followed by the impact, while the soil brightness index, the slope for the red-crowned crane nesting minimal impact32013Zhalong protected areas red-crowned crane unsuitable habitat area122518.29hm2, low suitable habitat area51624.36hm2, suitable habitat area31766.94hm2, the most suitable habitat area4090.41hm2, where appropriate and the most suitable habitat area and to35857.35hm2. Core areas, buffer zones, the most suitable experimental zone, the sum of suitable area was22776,5432,7648hm2, mainly in the range north to Keqin village, east ridge to the ox tail, horse farm, the County of reed field, south to the to the house, the old house to the west to the shack at home. A small amount of non-contiguous area located in the experimental area, namely the northern Wuyuer River, around the reservoir Dongsheng Yang deaf shack area, Liujiayao area, after five generations region, the southern region of northern Cui store to Majiahua house, Teller the southern to the northern region of tie Langer4through high MAXENT model results in habitat suitability index, the lower the nest site microhabitat data comparison, results show that vegetation height, diameter vegetation, vegetation density, interference distance, open water area of open water distance, the distance remaining reedbeds, the remaining area of reeds, reeds density residual remaining reeds height P values were less than0.05, there are differences. 52013Zhalong reed habitat protection zone area135348.84hm2, an increase of35727.54hm2in2004. In2013the total area of suitable habitat for protected areas accounted for17.08percent, an increase of3.18%over2004.2013Zhalong crowned crane capacity of the protected area is283pairs,191pairs compared to2004increased by92right,10years Zhalong protected areas suitable nesting habitat quality has improved to some extent, more conducive to the propagation of red-crowned cranes.
