This paper takes the remote sensing image of the fishery hole scenic area as the research object,and carries on the information interpretation research on the resource type according to the “Standards for the Extraction Method,Survey and Evaluation of Tourism Resources” issued by the Chinese National Standardization Committee in 2003.The main findings are as follows:(1)The processing of data sources loaded with DEM elevations has a significant impact on the interpretation of grassland grassland resources.With the increase of the mask area of ? ? the bare rocky gravel land,the dislocation rate and mis Extraction Method rate of the grassland grassland decreased,and the maximum likelihood Extraction Method of the multispectral data source after extracting gradient information was 0.82.Claim.Visual interpretation of human-computer interaction for the Happiness Garden has the function of small interpretation workload for the site selection of landslides with low landform and uncomplicated areas.(2)Slope tolerance and curvature tolerance processing have a significant impact on large-scale mountain peak resources.As the slope tolerance is set to a reduction of the 1curvature tolerance,the Extraction Method of terrain features can be effectively performed.(3)The selection of sample size and the processing of data sources have no obvious influence on the interpretation of natural scenes of Chinese waterscape resources.The two supervised Extraction Method methods involved in the Extraction Method have an impact on the results.For small water features,Xiaoxi River,and/or horses The accuracy of the two types of supervised Extraction Method cannot be significantly influenced by the fan shape,/dendrite shape,and/or radial shape of the river.For surveys in waterscapes,unobstructed remote sensing images above 5m resolution can be applied.(4)Sample size processing has a significant impact on the mis Extraction Method and leakage of broad-leaved forest resources and forest resources.With the increase of the sample size,the overall Extraction Method accuracy of the two plant communities has been significantly improved.The maximum likelihood Extraction Method method for125 sample sizes of the Yegupo Scenic Spot in the May Quarter-season scenic spot is88%..For an individual old tree ancient tree,no matter whether it is the improvement of training samples or the processing of data sources,the effect of overall Extraction Method accuracy is not obvious.Combined with visual interpretation,referring to the canopy scale and texture features,it can increase the degree of Extraction Method,showing that the laborious phenomenon cannot Interpretation of 0.61 m ground target ancient wood.(5)Mask processing has a significant effect on the extraction of the Stupa Cave Ornamental Park.With the cutting out of the area outside the viewing area,the reduction of the research area,and the interpretation of landmark buildings by prior knowledge,the maximum likelihood and neural network Extraction Method methods can achieve the effect of the Extraction Method accuracy and the KAPPA coefficient of 89 or more.(6)Mask processing has a significant impact on Class II buildings in the first-level cultural landscape.The spectral characteristics of the parking lot are easily misclassified by the first-grade road,and the phenomenon of “pepper and salt” appears.The data source after extracting the slope letter and road cutting combined with human-computer interaction can improve the Extraction Method time.The regular strip-shaped residential areas under the data source mask selected the training sample 100 to be higher than the sporadic traditional residential area.The interior architecture reduces the data source area,and the neural network Extraction Method accuracy increases to more than 80 to meet the applicable requirements.
