摘要
盐池县属宁夏中部生态环境脆弱典型区。从区域土地利用整体层面上评价了该县土地资源利用现状及经济效益,重点分析了该县土地资源利用现状、结构及土地利用格局特点,同时对该县各乡镇土地利用经济效益进行了评价,得出土地利用结构不合理,农业土地利用产出偏低等结论,并从持续高效利用角度提出了对策和建议。
The paper analyzes the present situation, structure and characteristics of land use patterns in Yanchi county, which is the typical area of ecologically vulnerable environment in central Ningxia . The exploration proved that there is abundant farmland resource while the majority of farmland is dryland on upland and plain, whose production is comparatively lower than the irrigable land; There is a large proportion of far-flung grassland with lower productivity, which is composed of semi-covered and lowly-covered grassland. The distribution characteristic of woodland is different in different regions, and the majority of it is shrubbery. Meanwhile the research explores the economic profit of 15 administration towns in the county, and it points out the problems existing in agricultural land use, including unreasonable land use structure, lower agricultural output and obvious regional economic differences. Furthermore, the paper presents the countermeasures to use land resources sustainably and effectively in Yanchi county.
