摘要:

云南是我国西部的典型山区省份,地形坡度<8°的坝区面积仅占土地总面积的6%左右。应用云南省第二次全国土地调查中对各县(市、区)≥1 km2坝子的调查和核定成果,选取坝区耕地面积比例、坝区土地面积比例、≥100 km2坝子数等3 个单项指标,并构建了综合指标——坝区土地综合指数,采用主导指标与综合分析相结合的方法,对全省129 个县(市、区) 进行坝区县、半山半坝县和山区县的划分。结果表明,全省有21 个县属于坝区县,37 个县属于半山半坝县,71 个县属于山区县。这一研究修订了以往云南省仅以坝区耕地面积比例为指标而划分出的坝区县、半山半坝县和山区县方案,为云南省及各地合理地进行产业布局(尤其是农业生产布局)、保护坝区优质耕地资源提供科学依据和基础支撑。

关键词: 坝区县, 坝区耕地面积比例, 第二次全国土地调查, 山区县, 坝区土地综合指数, 半山半坝县

Abstract:

Yunnan is a typical mountainous province in western China. Its flatland area with a terrain gradient of less than 8° accounts for about 6% of its total land area. A reasonable division of mountainous county, semi-mountainous county and flatland county is an important basic research task, which received considerable concerns from relevant departments and scientific and technological circles of Yunnan Province, for it's the basic foundation for industrial location (especially the location of agricultural production) and cultivated land resources protection in plain area. By using the verified result of the investigation of the flatlands area ≥ 1 km2 in various counties (cities, districts) of Yunnan during the Second National Land Survey, selecting three single indicators, including proportion of farmland in flatland area, flatland area proportion, and number of the flatlands with an area ≥ 100 km2, and constructing the comprehensive index of Comprehensive Index in Flatland Area (CIFA), and then adopting the method of combining leading indicators with comprehensive analysis, we divide the 129 counties (cities, districts) of the whole province into flatland counties, semi-mountainous and semiflatland counties, and mountainous counties. The division procedure can be separated into three steps: 1) Preliminary classification based on the leading indicators of CIFA; 2) proper adjustment according to the indicators as proportion of farmland in flatland area and flatland area proportion; and 3) adjustment again in accordance with indicator of number of the flatlands with the area ≥100 km2. The result shows that there are 21 flatland counties, 37 semi-mountainous and semiflatland counties, and 71 mountainous counties in Yunnan. This study revises Yunnan's previous plan to divide the counties into flatland counties, semi-mountainous and semiflatland counties and mountainous counties by relying solely on one indicator—proportion of farmland in flatland area. It offers scientific foundation and basic support to Yunnan Province and all places throughout the province for them to make rational industrial layout (especially agricultural production layout), and protect high-quality farmland resources in flatland areas.

Key words: semi-mountainous and semi-flatland county, Comprehensive Index in Flatland Area, proportion of farmland in flatland area, mountainous county, the Second National Land Survey, flatland county
