摘　　要：通过构建多目标数学规划模型,以乡村人居林林木覆盖指数、林木结构指数和林网密度指数最大化为目标,对福建省山区型、半山型、平地型和沿海型四类典型乡村人居林开展结构优化研究,结果表明:四类典型乡村人居林发展空间潜力巨大,优化后林未覆盖、林木结构和林网密度指数分别平均增加22.5221、40.8491和17.8571,结构趋向更加合理和科学.优化后的乡村人居林林木结构指数最高,总体平均可达91.5095,林木覆盖指数总体可达到较好水平60.6195,而林网密度指数总体也将显著提高到37.0130.村庄人居林发展潜力表明:半山型典型代表的茜黄村43.8222>沿海型典型代表的南书村24.9706>平地型典型代表的上浦村14.3479>山区型典型代表的扁山村10.9315.指数发展潜力呈现林木结构潜力>林木覆盖潜力>林网密度潜力的趋势.Constructed the multi-objective mathematical programming model,the objection was the maximize of cover index,structure index and networks index of village human habitat forest,this article carried out the structural optimization on four typical village human habitat forest of mountainous type,hill type,flat type and coastal type,the main results showed that four typical village human habitat forest will have great potential for development,the cover index,structure index and networks index of village human habitat forest can increase 22.5221,40.8491 and 17.8571,the structure become more reasonable and scientific.The structure index can reach a high level of 91.5095 after optimization,the overall index can reach a better level of 60.6195,the networks index will also be significantly increased to 37.0130.The development potential of the village tended that Xi huang village 43.8222>Nan shu village 24.9706>Shang pu village 14.3479>Bian shan village 10.9315.Tthe index development potential tended to structure potential index>cover potential index>density potential index.
