雄居内乡县北部伏牛山脊背南坡的宝天(山曼)森林自然保护区,位于北纬33°25′—33°33′,东经111°53′—112°00′,地处北亚热带向暖温带过渡地带,南北气候交错,地势高差起伏,山体海拔500—1845米,是河南省第一个自然保护区,由国营内乡万沟林场代管。整个林场有16个林区10866.7公顷,其中保护区的核心区有8个林区5400公顷。森林覆盖率达90％,林间平均郁闭度达0.8。根据河南农业大学、河南省林业勘察设计院、国营内乡万沟林场联合考察组1984—1986年的调查,本文对宝天(山曼)自然保护区森林生态效应,作初步的介绍和探讨。
Located in the north slope of Funiu Mountain in northern Neixiang County, Baotian (Shanshan) Forest Nature Reserve is located at latitude 33 ° 25’-33 ° 33’N and longitude 111 ° 53’-112 ° 00’E, and is located in the northern subtropical zone Transition zone to the warm temperate zone, north-south climate staggered, terrain ups and downs, the mountain elevation of 500-1845 meters, is the first nature reserve in Henan Province, by the state-owned township Mogou forest hosting. The entire forest farm has 16,666 hectares of forest area, of which the core area of the protected area has 8,400 hectares of forest area.
