基于综合评价的土地可持续利用时空特征分析——以四川省为例
|
摘要
四川人地矛盾尖锐是基本省情,为此,本文从资源、环境、经济、社会4个方面构建土地可持续利用评价模型,借助综合评价法与GIS技术分析四川省土地可持续利用时空特征.结果表明:2005—2014年四川省土地可持续利用指数呈缓慢上升趋势,除资源可持续指数呈现波动变化趋势外,环境、经济、社会和综合可持续指数总体呈上升趋势,其中环境可持续指数及增幅均低于经济、社会、综合可持续指数;土地可持续利用具有空间集聚性,土地利用经济、社会、综合可持续性空间分布具一致性,持续性水平较高地区主要集中在川西平原、川中丘陵,资源可持续性较高地区主要分布在成都平原、川南及川东北经济区,环境可持续性较高区域集中分布在川西北高原和川南山区.在土地可持续利用中,经济、社会因素起主导作用,资源、环境可持续性受自然条件影响较大,应兼顾经济、社会、资源、环境可持续协调发展.
The sharp man-land contradiction is a basic provincial reality of Sichuan.A sustainable land-use evaluation model was constructed on the basis of the four aspects of resources,environment,economy,society,and by use of the comprehensive evaluation method and GIS technology,a spatial-temporal characteristic analysis is made of the sustainable land use in the province.The result showed that the sustainable land use index is found to take a gradual rising trend.With the sustainable index taking a fluctuating trend,the other indices concerning the environment,economy,society and the comprehensive index are all taking an upward trend,of which the environment index and its increase amplitude are all less than the other three aspects;the land use sustainability displays a attribute of spatial aggregation,and comprehensive land use sustainability of economy and society is found to have a spatial consistency.The West Sichuan Plain and the Mid-Sichuan Hilly Area are found to have a relatively higher level of sustainability and spatial consistency,while the Chengdu Plain,the South Sichuan and the Northeast Sichuan Economic Zones are found to have a nice sustainability of resources,while the high environment sustainability is chiefly found in the Northwest Sichuan Plateau and the South Sichuan Mountain Area.The economic and social factors are found to play the dominating role in land use sustainability,and the environment and resource sustainability are liable to the impact of natural conditions.It is concluded that efforts should be made to achieve a balanced,coordinated sustainable development between economy,society,resources and environment.
