Amasu Okuphatha Amahlathi Aphumelelayo Okwandisa Ukukhiqizwa Kwezinkuni
Ukuphathwa kwehlathi okuphumelelayo kuyisihluthulelo sokwandisa ukukhiqizwa kwezinkuni ngaphandle kokubeka engcupheni ukusimama kwemvelo. Phakathi kwesidingo esikhulayo sezinto zokusetshenziswa embonini yezinkuni—kusukela ekwakheni nasefenisha kuya ephepheni—imikhuba emihle yokuphatha ayiseyona nje inketho, kodwa iyadingeka. Amahlathi aphethwe kahle angakhiqiza izinkuni ezisezingeni eliphezulu ngendlela eqhubekayo ngenkathi egcina imisebenzi yemvelo njengokugcinwa kwekhabhoni, ukuvikelwa kwenhlabathi, kanye nokuqina kwamanzi. Lesi sihloko sixoxa ngamasu okuphatha amahlathi asebenzayo okwandisa ukukhiqizwa kwezinkuni, kusukela esigabeni sokuhlela kuya ekuvunweni nasekubuyiselweni.
1. Ukuhlela Ukuphathwa Okusekelwe Kudatha
Isinyathelo sokuqala sokwandisa ukukhiqizwa kwezinkuni ukuhlela okujulile, okusekelwe kudatha. Kudingeka uhlu lwemithi ukuze kutholakale ukwakheka kwezinhlobo, ububanzi bemithi, ukuphakama, ivolumu yemithi, kanye nempilo yehlathi. Le datha isebenza njengesisekelo sokunquma imigomo yokukhiqiza, izinhlelo ezifanele zokulima izinkuni, kanye namashejuli okuvuna.
Ubuchwepheshe besimanje njengezithombe zesathelayithi, ama-drone, kanye nokumapha kwe-Geographic Information System (GIS) kusheshisa kakhulu futhi kuthuthukise ukunemba kwempahla. Ngamamephu amahle, abaphathi bangakwazi ukubona izindawo zokukhiqiza, izindawo ezivikelwe, imizila yezokuthutha, kanye nezindawo ezivame ukuguguleka noma izikhukhula. Ukuhlela okuningiliziwe kunciphisa imfucuza, kuvimbela ukulimala kwezihlahla, futhi kuqinisekisa ukukhiqizwa kwezinkuni okuhle ngokuhamba kwesikhathi.
2. Ukukhetha Uhlelo Olufanele Lokulima Izitshalo
I-silviculture isayensi kanye nobuchwepheshe bokusungula nokugcina izitendi zamahlathi ukuze kukhiqizwe imikhiqizo ethile, okuhlanganisa nezinkuni. Ukukhetha uhlelo lwe-silviculture olufanele kuthinta ngqo umkhiqizo. Ezinye izinhlelo ezisetshenziswa kakhulu zifaka:
– Ukusika nokutshala okukhethiwe (TPTI/TPTJ): ukusika izihlahla ezihlangabezana nezidingo ezithile zobubanzi, bese kuqinisekiswa ukuvuselelwa kwemvelo okufanele noma ukutshala kabusha. Lolu hlelo lufanelekela amahlathi okukhiqiza emvelo, luhlose ukugcina isakhiwo sokuma.
– Amahlathi ezitshalo: ukutshala izinhlobo ezikhula ngokushesha (isib. i-sengon, i-acacia, i-eucalyptus) ukuze kube nemijikelezo emifushane yokukhiqiza. Ukukhiqiza ukhuni kungakhuliswa kakhulu, kodwa kumele kulinganiswe nokuhlelwa komthelela emvelweni.
– Ukusika ngokushintsha indawo: Le ndlela isetshenziswa kancane futhi idinga ukucophelela okukhulu, ikakhulukazi maqondana nokuguguleka komhlabathi kanye nokulahlekelwa yindawo yokuhlala. Le ndlela isetshenziswa kakhulu ezindaweni ezitshalwe kahle ezinomhlaba ofanele.
Uhlelo olungcono kakhulu luncike ezimweni zendawo, uhlobo lomhlabathi, isimo sezulu, imigomo yokukhiqiza, kanye nezinqubomgomo nemithetho yendawo.
3. Ukukhethwa Kwezinhlobo Ezinhle Kakhulu kanye Nezinto Zokutshala Ezisezingeni Eliphezulu
Ukuze kwandiswe ukukhiqizwa kwezinkuni, ukukhethwa kwezinhlobo zezihlahla kanye nekhwalithi yezithombo kubalulekile. Izinhlobo ezinhle kakhulu ngokuvamile zikhula ngokushesha, iziqu eziqondile, ukumelana nezifo, kanye nekhwalithi yezinkuni ehlangabezana nezidingo zezimboni.
Izinto zokutshala kufanele zivela emithonjeni yembewu ethembekile neqinisekisiwe, njengezivande zembewu noma ama-clone angcono kakhulu. Ukusebenzisa izithombo ezisezingeni eliphezulu kunciphisa ukufa kwezitshalo, kusheshise ukukhula, futhi kukhiqize izithombo ezifanayo. Emahlathini okutshalwa kuwo izitshalo, ukukhethwa kwama-clone kanye nesikhala kungandisa kakhulu inani lezinkuni ngehektha ngalinye.
4. Ukulungiswa Kwendawo kanye Namasu Okutshala Asebenza Kahle
Emahlathini okutshalwa kwezitshalo, amasu okulungiselela umhlaba athonya ukukhula kokuqala, okunquma umkhiqizo wokugcina. Ukulungiswa komhlaba kudinga ukunakwa ekulondolozweni kwenhlabathi namanzi. Endaweni ethambekile, isibonelo, ukudala ama-terrace, amagquma, noma imichilo yokutshala ngemuva kwe-contour kunganciphisa ukuguguleka komhlaba.
Amasu okutshala kumele futhi abe nembambo, kusukela ekumbeni umgodi wokutshala, ukujula kokutshala, kanye nokufaka umanyolo wokuqala, uma kudingeka. Isikhala sokutshala sibalulekile ukunciphisa ukuncintisana phakathi kwezihlahla ngenkathi kwandiswa inani lezihlahla ezikhiqizayo. Kwezinye izinhlobo ezikhula ngokushesha, isikhala esifanele singabangela iziqu eziqondile kanye nobubanzi obufanele.
5. Ukunakekelwa Kwesitende: Ukususa Ukhula, Ukufaka Umquba, kanye Nokuvikela
Ngemva kokutshala, ukunakekelwa kuyisici esibalulekile ekwandiseni umkhiqizo. Ukuncintisana nokhula kungavimbela ukukhula, ikakhulukazi ezigabeni zokuqala. Ngakho-ke, ukhula lubalulekile, kungaba ngesandla noma ngomshini. Ukusetshenziswa kwemithi yokubulala ukhula kuyindlela yokukhetha, kodwa kufanele kucatshangelwe izinto zemvelo kanye nokuphepha.
Ukuvundisa kungandisa nokukhiqiza, ikakhulukazi enhlabathini engenazo izakhamzimba. Kodwa-ke, ukuvundisa kufanele kusekelwe ekuhlaziyweni kwenhlabathi kanye nezidingo zezinhlobo zezitshalo ukuqinisekisa ukusebenza kahle kanye nokuphepha kwemvelo. Ngaphezu kwalokho, ukuvikela amahlathi ezinambuzaneni, ezifweni, nasemililweni kumele kube yinto eza kuqala. Izinhlelo zokuthola kusenesikhathi, ukuqapha, ukuvimbela umlilo, kanye nemfundo yomphakathi kunganciphisa ingozi yokulahlekelwa okukhulu ngenxa yalezi ziphazamiso.
6. Ukunciphisa Ukunciphisa Ukuze Kuthuthukiswe Ikhwalithi Nomthamo
Ukunciphisa ukhuni kuyindlela ebalulekile yokuthuthukisa ikhwalithi yokhuni. Ngokunciphisa ubuningi bemithi, izihlahla ezisele zithola isikhala esiningi sokukhula, ukukhanya okwengeziwe, kanye nokufinyelela okungcono kwezakhamzimba. Lokhu kuphumela ekukhuleni kobubanzi obukhulu kanye nekhwalithi yesiqu ethuthukisiwe.
Ukuncishiswa kungenziwa ngezigaba eziningana kuye ngokuthi izihlahla zineminyaka emingaki. Izinkuni ezincishisiwe zingasetshenziswa njengezinkuni zokubasa umlilo, ubhontshisi, noma imikhiqizo yokhuni enobubanzi obuncane, okuhlinzeka ngemali engenayo eyengeziwe ngaphambi kokuvuna kokugcina. Ukuncishiswa okufanele kusiza ukwandisa inani lezinkuni ezinenani eliphezulu ngesikhathi sokujikeleza kokuvuna.
7. Ukubhalwa Kwemininingwane Encishisiwe
Ukuvuna okuphumelelayo nokungathinteki kakhulu kudlala indima ebalulekile ekugcineni umkhiqizo wesikhathi eside. Amasu okugawula izihlahla okuncishisiwe (RIL) agcizelela ukuhlela imizila yokuthutha, iziqondiso zokugawula, kanye nezindlela zokushelela ezinciphisa umonakalo ezihlahleni ezisele futhi zinciphise ukuphazamiseka kwenhlabathi.
Izinyathelo ezibalulekile ze-RIL zifaka phakathi ukumaka izihlahla zokugawula, ukwakha imigwaqo yokuthutha ehleliwe, ukulawula ukusetshenziswa kwemishini esindayo, kanye nokuqeqesha abaqhubi. Ngokunciphisa umonakalo endaweni esele, ukuvuselelwa kwamahlathi kuyasheshiswa futhi imijikelezo yokukhiqiza ingaqhubeka ngaphandle kokuwohloka komhlaba.
8. Ukuvuselelwa Nokuvuselelwa Ngemva Kokuvuna
Ukukhiqizwa kwezinkuni okusimeme akunakwenzeka ngaphandle kokuvuselelwa. Ngemva kokuvuna, indawo egawuliwe kumele ikwazi ukuvuselelwa ngokuvuselelwa kwemvelo noma ukutshalwa kabusha. Ukutshala okunothile kungenziwa ezindaweni ezingenazo izithombo noma ukwandisa ukwakheka kwezinhlobo zezinkuni ezinenani eliphezulu.
Ukuvuselelwa kuhlanganisa nokubuyisela imizila eyonakele yokushelela, ukulawula ukuguguleka komhlabathi, nokuvikela imithombo yamanzi. Uma kungalashwa ngemva kokuvuna, umkhiqizo womhlaba uzokwehla futhi izindleko zokuphatha zizokwanda ekujikelezweni okulandelayo.
9. Ukuzibandakanya Komphakathi kanye Nesitifiketi Sokuphathwa Kwamahlathi
Izici zomphakathi nazo zinquma impumelelo yokuphathwa kwamahlathi. Izingxabano zomhlaba, ukugawulwa kwemithi okungekho emthethweni, noma ukungenela ngokungemthetho kuvame ukuvela lapho imiphakathi ezungezile ingabandakanyeki. Ukubambisana nemiphakathi ngokusebenzisa amahlathi ezenhlalo, amahlathi ezolimo, noma izinhlelo zokwabelana ngenzuzo kungathuthukisa ukuqapha nokugcina ukusimama.
Izitifiketi ezifana ne-FSC noma i-PEFC (noma izindinganiso zikazwelonke ezifanele) nazo zikhuthaza imikhuba yokuphatha engcono. Ngaphandle kokuthuthukisa ukwethembeka kwemikhiqizo yokhuni emakethe, izitifiketi zidinga ukuhambisana nezindinganiso zemvelo nezenhlalo, ekugcineni kuqiniswe umkhiqizo wesikhathi eside.
Isiphetho
Ukwandisa ukukhiqizwa kwezinkuni akukhona nje ukugawula imithi eminingi. Isihluthulelo ukuphathwa kwamahlathi okuhleliwe, okuqhutshwa idatha, kanye nokusimeme. Ukukhetha uhlelo olufanele lokulima izihlahla, ukusebenzisa izithombo ezinhle kakhulu, ukunakekelwa okujulile, ukunciphisa, ukuvuna okungenamthelela omkhulu, kanye nokuvuselelwa ngemva kokuvuna konke kuyizindlela ezixhumene. Kuhlanganiswe nokusekelwa kwezobuchwepheshe, ukubandakanyeka komphakathi, kanye nokusetshenziswa kwezindinganiso zokuphatha, amahlathi angaba imithombo yokhuni ekhiqizayo neqhubekayo. Ngale ndlela, ukukhiqizwa kwezinkuni kuyanda, umnotho uyakhula, futhi umsebenzi wehlathi wemvelo ugcinwa ezizukulwaneni ezizayo.
