	Efficiency	Increased rate of land use $x_9$/%	$x_9=\frac{S1-S2}{S2}\times 100\%$, where $S1$ is the available land area after implementation of LCP, $S2$ is the available land area before implementation of LCP.	0.1217
		The annual increased output value of farmland $x_{10}/\left(\mathrm{yuan}·{\mathrm{hm}}^{-2}\right)$	$x_{10}=\frac{V1-V2}{AI}$, where $V1$ is the annual output value of farmland after implementation of LCP, $V2$ is the annual output value of farmland before implementation of LCP, $AI$ is the total area of LCP.	0.1544
		Increased grain production capacity $x_{11}/\left(\mathrm{kg}·{\mathrm{hm}}^{-2}\right)$	$x_{11}=\frac{G1-G2}{AI}$, $G1$ is the grain yield after implementation of LCP, $G2$ is the grain yield before implementation of LCP, $AI$ is the total area of LCP.	0.1215
		Increased rate in agricultural labor production $x_{12}$/%	$x_{12}=\frac{P1-P2}{P2}\times 100\%$, $P1$ is the agricultural labor productivity after implementation of LCP, $P2$ is the agricultural labor productivity before implementation of LCP.	0.0887
		Increment of land reclamation coefficient $x_{13}$/%	$x_{13}=\frac{CI}{AI}\times 100\%$, $CI$ is the increased cultivated land area, $AI$ is the total area of LCP.	0.0739
