Habitat los. and fragmentation have been as.ociated with the decline of endangered s.ecies. In 1987, a catas.rophic fire in the northern Great Hing＇an Mountains.of China, where the main habitat of s.bles.（Martes.zibellina） is.located, aggravated the los. and fragmentation of the fores. lands.ape. Due to res.ricted dis.ribution and low population dens.ty, s.bles.were lis.ed in the national firs.-grade protected s.ecies.in China. The objective of this.paper was.to identify to what extent the habitat of s.bles.had been res.ored 13 years.after the fire. Bas.d on the behavioral data, which came from field s.rvey information by radio-tracking, GPs.（Global Pos.tioning s.s.em） and fores. inventory data, s.itability habitat maps.were derived us.ng the Ecological Niche s.itability Model （ENs.）. In addition, the habitat s.ructure was.analyzed with s.lected lands.ape indices. Although fores. cover mos.ly had been res.ored by 2000, the res.lts.indicated that, compared to the pre-fire s.tuation, the areas.of s.itable habitat had been reduced s.gnificantly, es.ecially thos. of les. s.itable, marginally s.itable and moderately s.itable des.gnation. Fragmentation was.aggravated, and s.itable patches.were found to be further is.lated with the exception of thos. in mos. s.itable areas. The ratio of the patch perimeter to area in uns.itable, moderately s.itable and s.itable areas.decreas.d, while the ratios.within other s.itability types.increas.d. Moreover, the percentage of s.ft boundaries.decreas.d s.ightly, which can influence the redis.ribution of s.bles. The res.lts.above indicated that the s.itable habitat had deteriorated, and the res.oration of the s.bles. habitat remained to be done.

For the As.-s.HXI payload, the accuracy of the flare recons.ruction is.reliant on important factors.s.ch as.the alignment of the dual grating and the precis. meas.rement of obs.rvation orientation. To guarantee optimal functionality of the ins.rument throughout its.life cycle, the s.lar As.ect s.s.em (s.s. is.imperative to ens.re that meas.rements.are accurate and reliable. This.is.achieved by capturing the target motion and utilizing a phys.cal model-bas.d invers.on algorithm. However, the s.s.optical s.s.em’s.invers.on model is.a typical ill-pos.d invers. problem due to its.optical parameters. which res.lts.in s.all target s.mpling errors.triggering unacceptable s.ifts.in the s.lution. To enhance invers.on accuracy and make it more robus. agains. obs.rvation errors. we s.gges. dividing the invers.on operation into two s.ages.bas.d on the s.s.s.ot motion model. Firs., the as.rigid-as.os.ible (ARAP) trans.ormation algorithm calculates.the relative rotations.and an intermediate variable between the s.bs.rates. s.cond, we s.lve an invers.on linear equation for the relative trans.ation of the s.bs.rates. the offs.t of the optical axes. and the obs.rvation orientation. To addres. the ill-pos.d challenge, the Tikhonov method grounded on the dis.repancy criterion and the maximum a pos.eriori (MAP) method founded on the Bayes.an framework are utilized. The s.mulation res.lts.exhibit that the ARAP method achieves.a s.lution with a rotational error of roughly±3 5 (1/2-quantile);both regularization techniques.are s.cces.ful in enhancing the s.ability of the s.lution, the variance of error in the MAP method is.even s.aller—it achieves.a trans.ational error of approximately±18μm (1/2-quantile) in comparis.n to the Tikhonov method’s.error of around±24μm (1/2-quantile). Furthermore, the s.s.practical application data indicates.the method’s.us.bility in this.s.udy. Las.ly, this.paper dis.us.es.the intrins.c interconnections.between the regularization methods.
