九宫山位于幕阜山脉的中段,是赣鄂两省的分水岭,南坡在江西省的武宁县境内,北坡归湖北省的通山县管辖。目前,南坡的森林植被已遭破坏,北坡的相当繁茂,并已于1981年被通山县划定为自然保护区。九宫山北坡的地理位置为北纬29°20′—29°25′,东经114°33′—114°47′,植被区划属中亚热带常绿阔叶林区,但这里典型的常绿林很少,而以常绿树种为主要建群种的常绿落叶阔叶林却广泛分布。这些类型森林的种群结构状况如何?演替的趋向怎样?本文研究了这个
Jiugong Mountain is located in the middle of the Cuofu Mountain Range. It is a watershed between the two provinces of Jiangxi and Hubei. The southern slope is within Wuning County in Jiangxi Province and the northern slope belongs to Tongshan County in Hubei Province. At present, the forest vegetation on the southern slope has been destroyed, and the north slope has been quite prosperous. It was designated as a nature reserve by Tongshan County in 1981. The northern slope of Jiugong Mountain is located between 29 ° 20’-29 ° 25’N and 114 ° 33’-114 ° 47’E with vegetation sub-tropical evergreen broad-leaved forest areas, but the typical evergreen forest here is very Less, while evergreen deciduous broad-leaved forests with evergreen species as the main constitutive species are widely distributed. What is the population structure of these types of forests and what is the trend of succession?
