六安市裕安區耕地質量等別年度監測評價研究

摘 要：耕地質量等別監測評價是通過監測對耕地質量等別有影響的因素，分析耕地質量等別的變化趨勢。為掌握耕地質量的漸變規律，預測一定時期內的耕地質量變化趨勢，該文以裕安區為例，進行了耕地質量等別年度監測評價研究。首先在2016年監測成果的基礎上，進一步完善與確認省級耕地質量漸變類型集，在裕安區內確定典型的有代表性的漸變類型及分布范圍；再選取耕地質量漸變類型主導因素及驅動因子，在每種漸變類型區域內每個等別的耕地上選擇固定監測單元，追蹤耕地質量漸變過程；最后根據主導因素屬性值的變化評定耕地等別。研究結果表明，裕安區耕地質量漸變類型集可劃分為肥力提升型和逐步干旱型2種漸變類型，肥力提升型年度監測結果為等別降低，耕地質量提高；逐步干旱型等別提高，耕地質量下降。

Abstract：The monitoring and evaluation of cultivated land quality is to analyze the changes in cultivated land quality and other factors.In order to grasp the gradual change of cultivated land quality and predict the change trend of cultivated land quality in a certain period of time，take Yu'an District as an example to carry out annual monitoring and evaluation research on cultivated land quality.Firstly，based on the monitoring results in 2016，we will further improve and confirm the gradual types of cultivated land quality in the province，and determine the typical representative types and distribution ranges in the Yu'an District.Then select the dominant factors and drive factors of the gradual change of cultivated land quality.Factor，select fixed monitoring unit on each of the other cultivated land in each type of gradient type，track the gradual change process of cultivated land quality；finally，evaluate the cultivated land according to the change of the attribute value of the dominant factor.The research results show that Yu'an District has divided two types of fertility-enhanced and step-by-step drought types.The annual monitoring results of fertility improvement are lower，and the quality of cultivated land is improved.Gradually the drought type increases and the quality of cultivated land decreases.

Key words：Cultivated land quality；Grade；Monitoring；Evaluation；Yu'an district

耕地是人類生產生活的物質基礎，耕地質量決定了耕地的基礎生產能力，事關糧食安全及農業的可持續發展，是我國經濟發展和社會穩定的核心所在[1-2]。國內外學者對耕地質量評價進行了大量探索，但對于耕地質量等別監測評價的研究較少[3-4]。本研究以六安市裕安區為例，通過抽樣監測裕安區質量漸變耕地，全面掌握裕安區耕地的質量漸變類型、分布范圍及等別變化情況，分析區域內耕地等別和產能變化趨勢及變化原因，并為制定相關耕地保護政策提供依據[5]?！?br>
