年初（末）耕地面积 是指年初（末）统计区域内实有的全部耕地面积。

年内增加耕地面积 是指本年度因土地整理、复垦、开发、农业结构调整而增加的耕地面积。

土地整理 是指在一定区域内，按照土地利用规划，对田、水、路、林、村综合整治，提高农地质量，增加有效农地面积，改善农业生产条件和生态环境。其内容主要包括调整用地结构；归并零散地块；平整土地；道路、渠道等的综合治理；村庄及乡村企业用地的集中、搬迁和内部改造等。

土地复垦 是指对生产建设过程中挖损、塌陷、压占、污染等造成破坏的土地和洪灾、滑坡、崩塌、泥石流、风沙等自然灾害损毁的土地，采取生物和工程技术手段，使其恢复到可供利用状态的活动。

土地开发 是指按照土地利用规划，在保护和改善生态环境、防止水土流失和土地荒漠化的前提下，对滩涂、盐碱地、荒草地、裸土地等未利用地的宜农土地进行整治。

农业结构调整 是指由于经济发展和保护生态环境需要,在报告期对原有种植业、林业、牧业、水产养殖业、副业等所占土地在农业生产中所占比例进行调整。

农业结构调整（增加耕地） 是指由于农业结构调整，将原其他农业用途的土地改为耕地的面积。

年内减少耕地面积 是指本年度因建设占用、灾害损毁、生态退耕和农业结构调整而减少的耕地面积。

建设占用 是指因各类建设占用而减少的耕地面积。

灾害损毁 是指因水冲、沙压、山崩、泥石流、沟蚀、地震等自然灾害破坏而减少的耕地面积。

生态退耕 是指因生态环境建设需要，实际耕地退耕还林、还牧、还湖的面积。

农业结构调整（减少耕地） 是指由于农业结构调整，将原耕地改为其他农业用途土地的面积。

Explanatory Notes on Main Statistical Indicators

Cultivated land area at the year beginning (end) — refers to the area of all the cultivated land available within a geographic region of statistical surveys at the beginning (end) of the year.

Cultivated land area increased ring the year — refers to the area of cultivated land increased ring the year as a result of land consolidation, reclamation, new development, and agricultural restructuring.

Land consolidation — refers to the process of comprehensive renovation of farmland, water, roads, forests, and villages in a particular region according to land-use planning in order to raise the farmland quality, increase the effective farmland area and improve the conditions of agricultural proction and ecological environment. The content mainly includes land-use structure adjustment, consolidation of scattered parcels of land, land leveling, road and canal improvements, and concentration, relocation, and internal modification of land used for the construction of villages and village-and-town enterprises.

Land reclamation — refers to the process of restoring to the usable state the land damaged by excavation, collapse, surface land occupation, and pollution ring the proction and by natural disasters such as floods, landslides, avalanches, mud-flows, and wind-blown sand disasters by taking biotechnical and engineering technological means.

Land development — refers to the process of improving unused land suited to agricultural purposes such as shoals, saline-alkali land, land overgrown with weeds, and nuked land according to land-use planning in order to protect and improve the ecological environment, prevent soil erosion, and land desertification.

Agricultural restructuring — refers to the adjustment of the percentages of the lands originally used by crop growing, forestry, livestock farming, aquatic procts farming, and side-line occupation in agricultural proction ring the reporting period in order to meet the requirements for economic development and eco-environmental protection.

Agricultural restructuring (increase of cultivated land) — refers to the area of cultivated land to which the land for other agricultural uses is converted as a result of agricultural restructuring.

Cultivated land area reced ring the year — refers to the area of cultivated land decreased ring the year as a result of use for construction, damage by natural hazards, transfer of proctive cultivated land to ecological preservation uses, and agricultural restructuring.

Use for construction — refers to the area of cultivated land decreased e to various construction uses.

Damage by natural hazards — refers to the area of cultivated land decreased e to damage by natural hazards such as water erosion, sand coverage, landslides, mudflows, rill erosion, and earthquakes.

Conversion of cultivated land to ecological preservation uses — refers to the area of actual cultivated land converted for forestry, pasture, and lakes in order to meet the requirements for eco-environmental construction.

Agricultural restructuring (decrease of cultivated land) — refers to the area of land for other agricultural uses to which original cultivated land is converted as a result of agricultural restructuring.
