چکیده

The driving mechanism of soil quality (SQ) has important implications for arable land protection, sustainable agricultural development and ecological environment conservation. This study builds a “perception–response” theoretical framework to investigate how farmers’ use behavior may affect SQ from the temporal spatial perspectives. Based on sampling data, farmer survey data socioeconomic statistical collected in typical peri-urban area northeast China, geo-statistical analysis econometric models have been applied examine effect (FLUB) SQ. results show that during 1980–2010, target FLUB shifted “grain output maximization” profit then “profit maximization”. FLUB, including pattern, degree input intensity, also obvious differences space. These result distinct impacts variation time Generally, organic matter (OM) tends decline, available nitrogen (AVN) phosphorus (ANP) tend rise, while potassium (AVK) increases after an initial decline. Moreover, further distance city center, greater findings are not only helpful practical significance policy-makers improve outskirts metropolitan areas, but make contribution agriculture (PUA).
