本文把洛塔现存植被分为自然植被与栽培植被两大类进行研究，通过遥感技术对现存植被按针叶林、阔叶林、密灌、灌丛、草灌、荒草裸岩、农作物植被等类型进行分布面积的统计，在此基础上，以林产品价值、涵养水源价值、保护土壤价值和净化空气价值作为估算的主要参考依据，对已成林的针叶林与阔叶林进行森林生态系统的价值估算，得出面积为1388 . 8hm ~ 2的针叶阔叶林的森林生态价值为1836 . 37万元，参照这一生态价值量，把洛塔植被按常绿落叶林、针叶林、针阔混交林、阔叶林、疏林?灌丛、矮灌丛、荒草灌丛、经济作物和粮食作物，以每hm ~ 2的价值量提出了洛塔植被的综合价值体系。 - In quantitative terms , from the year of 1973 to 1990 , the absolute change extent obey the following sequence : dry field ( 8 . 61 % ) > shrub land ( - 7 . 06 % ) > paddy field ( - 3 . 52 % ) > naked land ( 2 . 12 % ) > tea land ( - 1 . 92 % ) > forest land ( 1 . 06 % ) > grassland ( - 0 . 61 % ) > rural settlement ( 0 . 58 % ) > traffic and industrial land ( 0 . 53 % ) > water ( 0 . 1 % ) > urban land ( 0 . 06 % ) ; and from 1990 to 2002 , dry field ( - 9 . 79 % ) > grassland ( 3 . 33 % ) > forest land ( 3 . 18 % ) > paddy field ( 1 . 98 % ) > naked land ( - 1 . 45 % ) > rural settlement ( 0 . 85 % ) > shrub land ( 0 . 73 % ) > water ( 0 . 48 % ) > traffic and industrial land ( 0 . 47 % ) > urban land ( 0 . 27 % ) > tea land ( 0 ) from the year of 1973 through 2002 , the cultivated land increased and then decreased
从数量上来看, 1973 1990年,变化幅度从大到小依次是旱地>灌木林>水田>裸岩地>其他林地>有林地>灌草地>农村居民点>交通工矿用地>水域>城镇用地; 1990 2002年则为旱地>灌草地>有林地>水田>裸岩地>农村居民点>灌木林>水域>交通工矿用地>城镇用地>其他林地。各地类的变化方向和强度存在较大差异。 1973年至2002年,耕地总量经历了先增后减的变化。
