| 摘 要： | 通过选取土地生产力、土地多样化程度指数、人均耕地面积、人均GDP等23个影响因子,并采用层次分析法对花江峡谷地区土地利用效果进行评价,以检验当前的土地利用模式是否适宜.测评结果表明,花江峡谷地区土地利用效果以查耳岩村最好,云洞湾、坝山、木工等次之,其它地区则较一般.与此同时,分析评价还证实了目前以经济林(草)种植为主的土地利用模式是适宜于花江峡谷地区的环境条件的.但是,花江峡谷地区土地利用效果很不均衡,有不少地区土地利用效果还比较差,仍需要进一步加强政策扶持与科技、资金及人才的投入.

| Abstract: | In order to test if the current land-use model is fit for local conditions or not,the land-use effect in Huajiang valley is evaluated by means of analytic hierarchy process on the basis of 23 affecting factors,such as land productivity,index of land-type diversity farmland area per capita and GDP per capita.It is showed that the land-use effect is best in Cha'eryan village,second in Yundongwan,Bashan and Mugong villages,and not so good in other villages.It is also proved that the current model of planting economic forest or grass is suitable for the local environments.But anyhow,the overall effects of land-use are not even,and the effects of land-use are lower in lot of area where still need to be helped by policy,science and technology,fund and qualified personnel. |
