文摘内容 For the healthy management of plantation, a health assessment indicator system was designed at forest stand scale for the larch plantation in Jin’ouling Forest Farm, Wangqing Forestry Bureau, Jilin Province. The system consisted of 3 categories—forest structure, external interferences and management objectives, with 15 indicators. The results showed that: 1) the assessment indicator system was scientific and rational for different age groups of larch plantations; 2) both the half-mature larch plantation and mature larch plantation were semi-healthy, while the near-mature plantation was healthy. The commons of all these plantations were structural integrity, little or no pest diseases and managed by appropriate operating activities; 3) the major problems included single tree species and relatively slow growing in the half-mature larch plantations; in the near-mature plantation, the number of grass species was less; and in the farm, the stock volume of mature plantations was below the average. Therefore, the half-mature larch forest should be thinned to improve the growth and the mature forest should be cut in time.
