衡阳市郊区位于衡阳盆地中部,为湖南的重要农业生产基地。由于植被反复遭受破坏,造成严重的水土流失,部分地方已沦为红色荒漠。根据水蚀地特点,探讨植被的恢复过程和演替趋势,对于依靠自然力恢复植被具有重要的意义。为了摸索这些规律,为封山育林恢复植被提供理论依据,我们在老师的指导下,结合森林生态学实习,对市郊、湘江、东洋渡等3个乡的植被恢复过程进行了调查测定,完成标准地54个,通过分析,初步报告如下:
Hengyang Suburb is located in the central Hengyang Basin, Hunan Province is an important agricultural production base. Due to repeated destruction of vegetation, resulting in serious soil erosion, in some places has become a red desert. According to the characteristics of water erosion, exploring the process of vegetation restoration and the trend of succession are of great significance to the restoration of vegetation by natural forces. In order to explore these laws and provide a theoretical basis for the restoration of hills and forests, we conducted a survey and determination of the vegetation restoration process in three townships in the suburbs, Xiangjiang River and Dongyangdu under the guidance of the teachers and forest ecology internships. A, through analysis, the initial report is as follows:
