Analysis on the Impact of Forest Resource Survey and Design on Forest Resource Protection—A Case Study of Shuangyashan City
Taking Shuangyashan City,Heilongjiang Province as an example,this paper analyzes the specific impact of forest resources investigation and design on forest resources protection.Based on the forest resources investiga-tion design,supplemented by literature research,investigation analysis and experience summary,the forest re-sources within the scope of the 4 forest farms in Shuangyashan,Heilongjiang Province were analyzed.The land types of the 4 forest farms in Shuangyashan,Heilongjiang Province were collected from 2018 to 2022,and the for-est age area and proportion as well as the forest protection level in different years were analyzed based on the sur-vey of forest resources in the past 5 years,it can find that:① the forest land types:the total area of forest farm,shrub land,suitable land and auxiliary production land increased year by year,while the area of dredge land,un-formed forest land,nursery land and non-forest land decreased year by year;② the area of different forest ages:the area of young and middle-aged forests gradually increases,and the proportion gradually increases;the area of near mature forests and mature forests gradually decreases,and the proportion gradually decreases;③ forest pro-tection grade:the proportion of Grade Ⅰ protected forestland increased year by year;the proportion of Grade Ⅱprotected forestland and Grade Ⅲ protected forestland did not change significantly,and the proportion of grade Ⅳprotected forestland gradually declined.Forest resources investigation design can clarify the content of forestry in-vestigation.Through the land type analysis,forest age structure analysis and forest protection grade analysis in a certain area,the general situation of forest resources in the region is understood in detail,and the forest resources protection work is reasonably done according to the investigation results,so as to realize the protection of forest resources.
