摘 要： 土地流轉(zhuǎn)過程中，綜合實力優(yōu)越的瓜菜種植承租商可使得流轉(zhuǎn)土地的產(chǎn)出與投入價值比得到較大提升。采用一種改進的CS-PP算法，將布谷鳥搜索算法優(yōu)異的非線性尋優(yōu)能力與投影尋蹤方法良好的高維數(shù)據(jù)處理能力結(jié)合，通過局部隨機搜索技術(shù)處理土地流轉(zhuǎn)過程中對瓜菜種植承租商的尋優(yōu)。結(jié)果表明，改進CS-PP算法的Q值大，目標(biāo)解的尋優(yōu)能力較強，優(yōu)于RAGA-PP算法與PSO-PP算法，可應(yīng)用于土地流轉(zhuǎn)過程中的瓜菜種植承租商尋優(yōu)嘗試。在不改變家庭承包經(jīng)營制度的基礎(chǔ)上，采用土地流轉(zhuǎn)方式將土地交給合適的瓜菜種植承租商運營，可實現(xiàn)第一產(chǎn)業(yè)由傳統(tǒng)向現(xiàn)代轉(zhuǎn)型，有利于公有制與市場的深度鉚合，更深層次地促進集體經(jīng)濟的發(fā)展。

Abstract： In the process of land circulation，the competent fruit planting tenants are more capable of achieving higher output and input value. In this paper，an improved CS-PP algorithm is used to combine the excellent nonlinear optimization ability of the cuckoo search algorithm with the high dimension data processing ability of projection pursuit method，therefore a partial random search technique is applied to find best potential fruit planting tenants in the process of land transfer. The improved CS-PP algorithm has larger Q value，stronger target solution，and is superior to RAGA-PP algorithm and PSO-PP algorithm，and can be used in the land transfer process of shortlisting fruit planting tenants. On the basis of not changing the family contract management system，using the land circulation method to transfer the land to the suitable tenants can uplift the transformation of agriculture industry from traditional to modern stage. It will also help the in-depth merging of public section and commercial market，thus to further promotes the collective economy development in deeper level.

1991年十三屆八中全會通過《中共中央關(guān)于進一步加強農(nóng)業(yè)和農(nóng)村工作的決定》，把家庭聯(lián)產(chǎn)承包責(zé)任制作為鄉(xiāng)村集體經(jīng)濟組織的一項基本制度長期穩(wěn)定下來。隨著家庭聯(lián)產(chǎn)承包責(zé)任制潛力消耗殆盡，其本身固有的缺陷逐漸顯現(xiàn)。2014年中央印發(fā)《關(guān)于引導(dǎo)農(nóng)村土地經(jīng)營權(quán)有序流轉(zhuǎn)發(fā)展農(nóng)業(yè)適度規(guī)模經(jīng)營的意見》，要求大力推廣農(nóng)村土地承包經(jīng)營權(quán)流轉(zhuǎn)制度。在非農(nóng)產(chǎn)業(yè)高收入的“拉力”和農(nóng)地經(jīng)營低收入的“推力”雙重作用下，農(nóng)戶參與土地流轉(zhuǎn)積極性增強，并表現(xiàn)出一定“自主性”[1]。國家一直重視農(nóng)業(yè)、農(nóng)民、農(nóng)村的三農(nóng)問題[2]。農(nóng)業(yè)現(xiàn)代化經(jīng)營的較大獲利空間以及國家對農(nóng)業(yè)企業(yè)扶持的常態(tài)化，為瓜菜種植承租商承包流轉(zhuǎn)土地提供了契機。……
